RATIO AND PROPORTION
Direction: Complete the equal ratios.
Answer:
Step-by-step explanation:
All we have to do is to multiply the extremes and means. The extremes are the outside numbers and the means are located on the inside.
1) 8:__ = 14:35
n × 14 = 8 × 35
14n = 280
n = 20
2) 5:7 = __ :35
7 × n = 5 × 35
7n = 175
n = 25
3) 36:__ = 8:6
n × 8 = 36 × 6
8n = 216
n = 27

Answer:
Required Answer :-
1] Let the number be x
8:x = 14:35
8 × 35 = 14x
280 = 14x
280/14 = x
20 = x
2] 5:7 = x:35
5 × 35 = 7x
175 = 7x
175/7 = x
25 = x
3] 36:x = 8:6
36 × 6 = 8x
216 = 8x
216/8 = x
27 = x
