Question

C is directly proportional to D, when C-125 and D=5. Work out the value of C when D = 6. Work out the value of D when C = 4725

Answer 1

d=189 when c=4725

Explanation:

c:d

125:5

divide by 5 to find the value of c when d=1

25:1

multiply by 6 to find the value of c when d=6

150:6

4725:?

4725/25=189

189*1=189
