Write two division expression s that have the same vaule as 36.8 ÷ 2.3

Triss [41]

<h3>Write two division expression s that have the same vaule as 36.8 ÷ 2.3 </h3>

$32 \div 2 = 16\\\\48 \div 3 = 16$

Solution:

Given that,

We hve to find the two division expression s that have the same vaule as 36.8 ÷ 2.3

From given,

$36.8 \div 2.3 = 16$

So, we have to find two division expressions that has a value of 16

First division expression

We know that 32 divided by 2 gives 16

Thus, we can write as,

$32 \div 2 = 16$

Second Expression:

We know that 48 divided by 3 gives 16

Thus, we can write as,

$48 \div 3 = 16$

Thus the two expressions are found
