Answer 2

(4÷15)÷(9÷10)=4×10/15×9=40/135=8/27

Answer 3

To solve the expression (4:15):(9:10), we need to understand what the colon (:) represents in this context. In mathematics, the colon is often used to represent a ratio or division.

In this case, (4:15) means 4 divided by 15, and (9:10) means 9 divided by 10. So, we can rewrite the expression as:

(4:15):(9:10) = (4/15) / (9/10)

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is obtained by swapping the numerator and denominator.

So, we have:

(4/15) / (9/10) = (4/15) * (10/9)

Now, we can multiply the numerators and denominators:

(4/15) * (10/9) = (4 * 10) / (15 * 9) = 40/135

The simplified form of 40/135 is 8/27.

Therefore, (4:15):(9:10) is equal to 8/27.
