Answer:
The sum of the numbers is <em>132</em>
Step-by-step explanation:
First find the smallest number
- 3/8=x/96
- 2(96)=8x
- 288=8x
- x=36
Thus, you found the smallest number
then there sum given as 96+36=132
Yes they are because you use distributive property and 4(x+y) you have to do 4•x= 4x and 4•y=4y so it would be 4y+4x

<h2>Rounding-off percentage</h2>
Let the student got total number of problems in the test to be X.
Percentage of correct answer = 39 %
⇒ 61% of X were incorrect
⇒61/100 x X = 45
⇒61X = 45x100
⇒X = 4500/61
⇒X=73.77
After rounding off 73.77, we get 74.
Hence, we can say that there were total of 74 problems in the test.
