Question

parineeta spent 3 3/4 hour in doing her home work if she gave 1 1/2 hour to mathematics find the time spent in doing the work of other subject ​

Answer 1

Step-by-step explanation:

Total time spent in doing homework = 3¾

time spent in doing math homework = 1½

time spent in doing other subject = total time spent - time spent in math hw

3¾ = 15/4

1½ = 3/2

15/4 - 3/2 = 30/8 - 12/8 (equalizing the denominator)

=18/8

=2.25 hours

Step-by-step explanation:

$\huge{\fcolorbox{yellow}{red}{\large{\fcolorbox{blue}{pink}{{\fcolorbox{orange}{aqua}{✨ANSWER✨}}}}}}$

→ Total time spent in doing homework = 3¾

→ time spent in doing math homework = 1½

→ time spent in doing other subject = total time spent - time spent in math hw

→ 3¾ = 15/4

→ 1½ = 3/2

→ 15/4 - 3/2 = 30/8 - 12/8 (equalizing the denominator)

→ 18/8

→ 2.25 hours Ans
