उत्तर
A ribbon of length `5 1/4` m is cut into small pieces each of length `3/4` m. Number of pieces will be 7.
Explanation:
Number of pieces = `"Total length of ribbon"/"Length of one piece"`
= `((5 1/4))/((3/4))`
= `((((5 xx 4) + 1)/4)/(3/4))`
= `((21/4))/((3/4))`
= `21/4 xx 4/3` .......`[∵ "Reciprocal of" 3/4 = 4/3]`
= 7
