Question

2145/2688 simplification ​

Answer 1

$solution$

A:B = 11:12 and B:C = 13:14. They become

A:B = 143:156 and B:C = 156:168. Or

A:B:C = 143:156:168

Next, B:C = 13:14 and C:D = 15:16. They become

B:C = 195:210 and C:D = 210:224. Or

B:C:D = 195:210:224

A:B:C = 143:156:168 = 178.75:195:210.

A:B:C:D = 178.75:195:210:224.

Hence A:D = 178.75:224 or 17875:22400 = 715:896

Factors of

715 = 5x11x13

896 = 2x2x2x2x2x2x2x7

HCF = 1. So further reduction is not possible.

Answer 2

• As per the data given in the question, we have to find the value of the expression.

           Given data:- $\frac{2145}{2688} .$

           To find:-The value of the expression.

           Solution:-

• Division means a number that is divided into two parts.
• We know that division is denoted by ($\div$).
• Properties of division are as follows

1. Property of Zero.
2. Property of one.
3. Identity property of one.

        Therefore.

            $\frac{2145}{2688} .\\=0.7979.$
