Q 4.SOLVE THE WORD PROBLEMS, MAKING COMPLETE  STATEMENTS.

(a) In a relay race, I6 children

ran a total of 9600 m. How

many metres did each child

run?

Solution:

Total children=16

Total race=9600m

Each child ran= 9600÷16

=600 meters

(b)A jug contains 1440 ml of

orange juice. If I2 children

share the juice equally, how

much does each child get?

Solution:

Total children=12

Total juice=1440 ml

Each child got= 1440÷12

=120 ml

(c)If crayons are packed in

boxes of I6, how many

boxes are needed to pack

4000 crayons?

Solution:

Total boxes=16

Total crayons=4000

Each child ran= 4000÷16

=250 crayons

(d)Rs 5530 is collected for 7

families whose homes have

been damaged by floods.

How much money will each

family get?

Solution:

Total families=7

Total money=Rs 5530

Each family got= 5530÷7

= Rs 790

(e)Eleven children share the

first prize in a painting

contest. If the prize money is

Rs 5000, how much will each

child get, and how much

money will be left over?

Solution:

Total children=11

Total money=Rs 5000

Each child got= 5000÷11

= Rs 454  left over =6
