Which of the following pairs consist of equivalent fractions?
a. 9/16 and 20/32
b. 7/10 and 10/7
c. 4/6 and 3/5
d. 18/48 and 15/40

d

Step-by-step explanation:

a is incorrect because

20/32=10/16=5/8

b is incorrect because

10/7=1.42 and 7/10=0.7 which don't equal each other

c is incorrect because

4/6 equals 2/3 not 3/5

d is correct because,

18/48=15/40

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
