Question

What portion of a ‘saree’ can Rehana paint in 1 hour if it requires 5 hours to paint the whole saree? In `4 3/5` hours? in `3 1/2` hours?

Answer 1

In 5 h, Rehana paints = Whole saree

In 1 h, She paints = `1/5` part of saree

In `4 3/5` h, She paints = `1/5 xx 4 3/5`

= `1/5 xx ((5 xx 4) + 3)/5`

= `1/5 xx 23/5`

= `23/25` part of saree

In `3 1/2` h, She paints = `1/5 xx 3 1/2`

= `1/5 xx ((3 xx 2) + 1)/2`

= `1/5 xx 7/2`

= `7/10` part of saree
