Question

If x : 8 : : 5 : 4, then x = 20
state True or False and explain​

Answer 1

Answer:

False, x= 10

Step-by-step explanation:

The product of outcomes= The product of incomes.

Here the outcomes, 1 is given but the other one is not given .

So, we should consider the incomes here 8, 5. Here if we multiply then we get 40.

So, x=

x:8::5:4

Ratios are fractions

$\frac{x}{8} = \frac{5}{4 } \\ x = \frac{5}{4} \times 8 \\ x = 5 \times 2$

by cancelling 4 and 8 using 4 table.

x=10
