Answer:

For example:

(i) Multiply 129 by 25

Solution:

129 × 25

= 1×9+29

= 119 × 25

= 11×259

= 2759

= 3059

(ii) Multiply 2/3 by 7

Solution:

2/3 × 7

= (2 × 7)/3

= 14/3

= 4 2/3

We simply multiply the numerator of the fractional number by the whole number. The denominator remains the same.

(iii) Multiply 2 3/5 by 6

Solution:

2 3/5 × 6

= (2 × 5 + 3)/5 × 6

= (10 + 3)/5 × 6

= 13/5 × 6

= (13 × 6)/5

= 78/5

= 15 3/5
