Answer:
60
Step-by-step explanation:
A decrease in the ratio 3 : 4 implies that
new value : old value = 3 : 4
x : 80 = 3 : 4
x/80 = 3/4
x = 3/4 * 80
= 3 * 20
= 60

The answer of 3.2+4.67 is:
decimal form: 12.87
fraction form: 12 87/100
Answer:
multiply by the reciprocal of 31/6
Step-by-step explanation:
4 and one-third = 4 1/3
5 and StartFraction 1 over 6 EndFraction = 5 1/6
Therefore,
4 1/3 ÷ 5 1/6
= 13/3 ÷ 31/6
To solve the problem, multiply 13/3 by the reciprocal of 31/6
The reciprocal of 31/6 = 6/31
So,
13/3 ÷ 31/6
= 13/3 × 6/31
= (13 * 6) / (3 * 31)
= 78 / 93
= 26/31
