Draw and explain how you can use a number line to rename a fraction greater then 1 as a mixed number
Answers
Consider the number .
Since the numerator is greater than the denominator, this fraction is greater than 1.
Now, in the number line, find out how many 13's are there within 27.
The answer is 2.
Now, subtract 2 × 13 from 27.
27 - 26 = 1
Hence, the required mixed fraction is
Solution:
Consider a Mixed fraction greater than 1, where , b>a.
To represent it on the number line
1. Divide or mark b-1 points between 1 and 2.
2. So, if you have to mark , , start writing on number line as
,
,
,..and finally mark
.
Now suppose you have to represent on number line.
Following the procedure described above
1. Mark four points between 1 and 2.
2. The first point is and second point is
. Last one is
.
Now, Suppose the fraction is and you have to write it in terms of mixed fraction
Use the Euclid Lemma to write it as mixed fraction
That is , a= b ×q +r, when natural number a is divided by b gives q as quotient and r as remainder,
123 = 15 × 8 + 3

Answer:
B
Step-by-step explanation:
We start with 16 grams of water
At the end of the first hour , we decreased by 3.5%
We take the amount and multiply by the percent decreased. Then subtract that from the original amount
16*3.5% =
16*.035 =.56
16-.56 = 15.44
At the end of the second hour , we decreased by 4.25%
We take the amount and multiply by the percent decreased. Then subtract that from the amount we started with at hour 2
15.44 *4.25%
15.44 *.0425=.6562
15.44-.6562=14.788
Answer:
B.
Step-by-step explanation:
So there are 16 grams initally. Then, the amount of water decreases by 3.5%.
So first we must find 3.5% of 16. 3.5% in decimal form is 0.035, since you divide 3.5 by 100. Then, when you multiply 0.035 by 16, you get 0.56. Since the solution decreased by that percentage, you must subtract 0.56 from 16, which is 15.44.
Then the amount of water decreases by 4.25%. That in decimal form is 0.0425. You multiply it by 15.44, and it comes out to 0.6562. You subtract that from 15.44, not 16, since some of the water has evaporated. So you get 14.7838.

Answers
32(1/4)=8
32 × t = 8
t = ?
8 ÷ 32 = t
8 ÷ 32 = 0.25
t = 0.25
CHECK OUR WORK:-
32 × t = 8
t = 0.25
32 × 0.25 = ?
32 × 0.25 = 8
We were RIGHT!!!
So, t = 0.25.
Hope i helped ya!! xD
