A.
9 × 16 × 10 = f

B.
9 × (16 × 10) = f

C.
(9 × 16) + (9 × 10) = f

D.
(9 + 16) × (9 + 10) = f

Answers

Answer 1

Answer: C. Because there's 16 of one flower and 10 of the other on 9 necklaces... You could also use: (16+10) X 9 = f :)

Answer 2

Answer: a I believe if not sorry

Given that, Noelle has 5/6 of a yard of purple ribbon and 9/10 of a yard of pink ribbon.

What is addition of two fractions?

To add fractions there are three simple steps:

Step 1: Make sure the bottom numbers (the denominators) are the same. Step 2: Add the top numbers (the numerators), put that answer over the denominator.

Step 3: Simplify the fraction (if possible)

Total number of yards of ribbon

= 5/6 + 9/10

LCM of denominators 6 and 10 is 30

Now, 25/30 + 27/30

= 52/30

= $1 (22)/(30) =1(11)/(15)$

Therefore, the total length of the purple ribbon and pink ribbon is $1(11)/(15)$ .

add 5/6 and 9/10
first look for a common denominator....that's....30
so now the fractions are 25/30 + 27/30
add the numerators keep the common denominator.
52/30 in mixed number is 1 22/30, now reduce the fraction, divide by 2, so
1 11/15, so Noelle has 1 11/15 ribbon altogether.

Try to simplify 72/6+85/6

Answers

72 + 85 = 157

157/6 = 26
26*6 = 156
26 and 1/6

Answer: 26 and 1/6

72/6+ 85/6
= (72+ 85)/6
= 157/6
= (156+1)/ 6
= 156/6+ 1/6
= 26+ 1/6
= 26 1/6

The final answer is 26 1/6~

Round the number 347 500 to the nearest 1000, 10 000 and 100 000

Answers

The rounded form of 347500 for given cases gives 348000, 350000 and 300000.

What is rounding a number to some specific place?

Rounding some number to a specific value is making its value simpler (therefore losing accuracy), mostly done for better readability or accessibility.

Rounding to some place keeps it accurate on the left side of that place but rounded or sort of like trimmed from the right in terms of exact digits.

For this case, we've got the number 347,500

Rounding it for given cases:

Case 1: Rounding it to the nearest 1000,

Rounding to nearest thousand means rounding to the digit whose value is in thousands (from 0 to 9).

This is the fourth digit from right of the decimal.

347500 = 347500.0

The fourth digit from right is 7

Rounding to it, as it has 5 next to it, the rounded version will make 7500 -> 8000

Thus, we get:

347500 -> 348000

Similarly,

Case 2: Rounding to nearest 10000

There are 5 digits in 10000, and 5th digit from right in 347500 is 4

Right to 4, there is 7, which is ≥ 5, therefore, 47500 will become 50000

Thus, we get:

347500 -> 350000

Case 3: Rounding to the nearest 100000

6th digit from right in 347500 is 3.

Right to 3 lies 4. 4 < 5 therefore 347500 will become 300000 after rounding to the nearest 100000

The digit 5 acts as a limit.

If the right sided digit to the digit where we've to round off is < 5, we keep it same and make all right sided values 0, and if the right sided digit is > 5, then we make it increase by 1 and rest of the right sided digits become 0. If the digit on right is 5, and after it there is only zeros or no value, then we round up (increase by 1, as we did in 347500 -> 34800 ) (Well there are many detailed rules of rounding)

Thus, the rounded form of 347500 for given cases gives 348000, 350000 and 300000.
