Question

The weight of 56 books is 8 kg. What is the weight of 112 such books? How many such books weigh 5 kg?​

Answer 1

since, weight of 56 books = 8kg

so , weight of 1 book = $\frac{8}{56}$ = $\frac{1}{7}$kg

therefore,

weight of 112 books = $\frac{1}{7}$ × 112

= $\frac{112}{7}$

= 16 kg

And ,

number of books weigh 8 kg = 56

then, number of books weighs 1 kg = $\frac{56}{8}$ = 7

thus ,

number of books weighs 5 kg = 7 × 5 = 35 books !
