Multiply 20/5 by nine so 20/5 simplify into 4 4 times nine is 36, so only 36 kids liked the book
Step-by-step explanation:
There would be 60 questions on the test.
90%=54
1%= 54/90 = 6/10
100%= 6×100/10 =6×10=60
It wouldn't let me post the answer. See images for the answer and explanation
Well, we know perimeter is just adding all the lengths together.
And we already know 2 of the lengths, so we know the rest. 11 1/2 is the same as the opposite side, and 6 1/3 is the same as the opposite side.
So the sides are 6 1/3, 6 1/3, 11 1/2, 11 1/2.
Add them up:
6 1/3 + 6 1/3 + 11 1/2 + 11 1/2.
Improper fractions:
19/3 + 19/3 + 23/2 + 23/2.
Common denominator, (6):
38/6 + 38/6 + 69/6 + 69/6 = 214/6.
Simplify:
214/6 = 35 2/3
