Answer 2

Answer:

To find the least common denominator (LCD) of 3/8 and 8/5, we can use the method of prime factorization.

Prime factorization of 8: 2 x 2 x 2

Prime factorization of 5: 5

To get the LCD, we need to include all the prime factors from both denominators, including duplicates:

LCD = 2 x 2 x 2 x 5 = 40

Now we need to convert both fractions so that they have a denominator of 40:

3/8 x 5/5 = 15/40

8/5 x 8/8 = 64/40

Now both fractions have a denominator of 40, and we can compare them more easily. The two fractions are:

15/40 and 64/40

So the LCD of 3/8 and 8/5 is 40.

May I please have a Brainliest? I put a lot of thought and effort into my answers, so I would really appreciate it!

Can someone please help me with this ASAP

Answers

there are 25 grandparents there were in the survey. 4 prefered digital copies, 21 prefered hard copies.

4/25 prefered digital copies
21/25 prefered hard copies

21 is more than 4.
The only one of the possible answers that imply that more people prefered hard copies was the third option. Therefore, "More grandparents prefer using a hard copy than a digital copy." is the most likely to be true.

The difference is 31 cm³

Step-by-step explanation:

To solve the volume a cube it's a³

5.7³ = 185.193

I'm assuming to round to the nearest whole number so the difference would be

216 - 185 = 31

when the whole is the same why does it take 4 copies of one tenth to equal 2 copies of one fifth draw a model to support your answer

Answers

well 4 copies of one tenth will equal 4 tenths. so when u simplify 4 over ten (4/10 )and divide the top and bottom by the common factor which is 2 then you will get 2 fifths because 4 divided by 2 is 2 and 10 divided by 2 is 5.
