Answer 2

The given question is How many metres of ribbon does he has in total?

(a)55m

(b) 65m

(c) 75m

(d) 85m

It is given that Ramu has four full rolls of ribbon and one roll of ribbon is 18 3/4 m long.

The length of one roll of ribbon is given as

$18 \times \frac{3}{4}$

we have to find how many rolls he had in a total of 4 rolls

The total length in 4 rolls is obtained by multiplying the length of one roll of the ribbon by the digit 4.

$4\times (18 \times \frac{3}{4} ) = 4 \times \frac{75}{4}$

The mixed fraction is changed into an improper fraction.

we have to perform a normal multiplication operation.

If the number 4 multiplies the division will be cancelled?

$4 \times \frac{75}{4} = 75$

The answer obtained is 75.

Therefore, the final answer to the given question is 75m

The correct option is (c).
