Given: Friday, Lisa spent five hours completing her mathematics homework, science homework and drawing a picture. She spends one-fifth of the time doing her mathematics homework and two-fifth of the time doing science homework and the rest of the time drawing a picture.
To Find: How much time did she use to complete her mathematics homework and draw a picture.
Solution:
Total hours spent by Lisa= 5 hours
Time spent by Lisa on maths = 5×1/5 = 1 hour
Time spent by Lisa on science = 5× 2/5 = 2 hours
Time spent by Lisa drawing pictures = 5-(1+2)
= 2 hours
Therefore, the time Lisa spent completing her mathematics homework and drawing a picture = 1+2 = 3 hours
Therefore, the time Lisa took to complete her mathematics homework and to draw a picture is (c) 3 Hours.
