Question

Q5.
Twenty tiles weigh 5 kg. How much do 7 tiles weigh?
{Hint: convert kg to g)​

Answer 1

Answer:

20 tiles = 5 kg · 1 tile = 5/20 kg = 1/4 kg · 7 tiles = 1/4 x 7 = 7/4 kg · 5 kg = 20 tiles · 1 kg = 20/5 = 4 tiles ·

12 kg = 4 x 12 = 48 tiles

Answer 2

Answer:

Explanation:

20tiles weigh = 5kg

so 1 tile weight is =5/20kg

=0.25 kg

then weight of 7tiles =7×0.25

=1.75kg

if a man want to carry a weight of only 12kg

then he will carry = 12/0.25 tiles

=48 tiles.
