The statement that the numbers 8 , 10 , 4 , 5 are in proportion is true

Given :

The statement 8 , 10 , 4 , 5 are in proportion

To find :

To check true / false the statement

Solution :

Step 1 of 3 :

Write down the given numbers

The given numbers are 8 , 10 , 4 , 5

Step 2 of 3 :

Write down the condition for proportion

Four given numbers a , b , c , d are said to be in proportion if product of extreme terms = product of middle terms

That is , a × d = b × c

Step 3 of 3 :

Check whether 8 , 10 , 4 , 5 are in proportion

Extreme terms are 8 & 5

Middle terms are 10 & 4

Product of extreme terms = 8 × 5 = 40

Product of middle terms = 10 × 4 = 40

Thus we observe that

Product of extreme terms = Product of middle terms

So 8 , 10 , 4 , 5 are in proportion

Hence the statement that 8 , 10 , 4 , 5 are in proportion is true
