Answer 2

Answer:

Concept:

Rational numbers

p/q of two integers with q ≠ 0 can be used to represent a number as a rational number in mathematics. The set of rational numbers also contains all of the integers, which can each be expressed as a quotient with the integer as the numerator and 1 as the denominator.

Step-by-step explanation:

Cloth needed for 1 child = $\frac{3}{5}$ meter

So by multiplying the quantity of cloth and number of children

Cloth needed for 200 children = 200 × $\frac{3}{5}$

                                                   = 120 meters

So the clothe needed for 200 children for designer is 120 meters.
