A. 9
B. 24
C. 6
D. 16
Step-by-step explanation:
Given ratios are;
A. 2 : 3 = 6 : x
Product of mean = Product of extreme
Dividing both sides by 2
B. 4 : 7 = x : 42
Product of mean = Product of extreme
Dividing both sides by 7
C. 2x : 48 = 3 : 12
Product of extreme = Product of mean
Dividing both sides by 24
D. 12 : 15 = x : 20
Product of mean = Product of extreme
Dividing both sides by 15
Let m stand for number of minutes
.12m+2=25.04
.12m-2=25.04-2
.12m=23.04
.12m÷.12=23.04÷.12
m=192
The number of minutes is 192 minutes.
Hope that helps you!!
31/50 is the correct answer. It began at 62/100 but you must reduce
