Step-by-Step Solution

To solve the given expression 220:(15×8) 220 : (15 \times 8) , follow these steps:

  • Step 1: Calculate the multiplication inside the parentheses: 15×8 15 \times 8 .

  • Step 2: Divide 220 by the result obtained from Step 1.

Let us perform the calculations:

Step 1: Calculate the multiplication.
15×8=120 15 \times 8 = 120 .

Step 2: Divide 220 by 120.
So, 220÷120=220120 220 \div 120 = \frac{220}{120} .

To simplify 220120\frac{220}{120}:

Divide both the numerator and the denominator by their greatest common divisor (GCD), which is 20.

The division yields:
220120=11×206×20=116\frac{220}{120} = \frac{11 \times 20}{6 \times 20} = \frac{11}{6} .

This fraction 116\frac{11}{6} can be expressed as a mixed number by dividing 11 by 6:

- 11 divided by 6 equals 1 with a remainder of 5, so:

156 1\frac{5}{6} .

Thus, the solution to the problem is 156 1 \frac{5}{6} .

Answer

156 1\frac{5}{6}
