A. Solve for the missing term.
1. 3:5 = __:30
2. 5:7 = __:14
3. __:14 = 16:28
4. 6:__ = 18:12
5. 10:5 = 18:__​

Sagot :

Answer:

A proportion is a statement that two quantities are equal.

If two ratios are equal, then

a:b = c:d

•a and d is product of extremes

•b and c is product of means

SOLUTION:

1.) 3:5 = __:30

30÷5=6

Therefore, 3×6= 18.

The missing term is 18.

2.) 5:7 = __:14

14÷7= 2

Therefore, 5×2= 10

The missing term is 10.

3.) __:14 = 16:28

28÷14= 2

Therefore, 16÷2=8

The missing term is 8.

4.) 6:__ = 18:12

18÷6= 3

Therefore, 12÷3=4

The missing term is 4.

5.) 10:5 = 18:__

10÷5= 2

Therefore, 18÷2= 9

The missing term is 9.
