Question

find the value of a,b,c,d in5/4=a/16=25/b=-15/c=d/28​

Answer 1

Answer:

A = 20, B = 20, C = - 12 and D = 35

Step-by-step explanation:

a/16 = 5/4

By cross multiplication -

4a = 80

a = 80/4 = 20

25/b = 5/4

By cross multiplication -

100 = 5b

b = 100/5 = 20

-15/c = 5/4

By cross multiplication -

5c = -60

c = -60/5 = -12

d/28 = 5/4

4d = 140

d = 140/4 = 35
