Explain how scaling a mixed number by 1/2 will affect the size of a number
JulsSmile [24]
<span>If the mixed number is scaled by 1/2 then, the original number will be divided by 2. That being said, the number then becomes 50% of the original value. Hence, scaling the number by 1/2 will make the number only 50% of its original value. </span>

If the reciprocal of the number $X$ equals $\frac{2}{7}$, what is $5$ divided by $X$?
grigory [225]
U can find the reciprocal of a number by flipping the number.
example : the reciprocal of 1/5 is 5/1....the reciprocal of 2/3 = 3/2.

the reciprocal of x = 2/7.....that means x = 7/2

5 / (7/2) = when dividing fractions, flip what u r dividing by, then  multiply
5 * 2/7 =
10/7 or 1 3/7 <==
