Let:
Step 1: Put the fractions altogether.
Step 2: Find the LCD or Least Common Denominator.
4 x 5 = 20 x 3 = 60
LCD: 60
Put each denominator into 60 by multiplying a number that will put them into 60.
Every hour has 60 minutes so we need to make the fraction into a mixed number.
Therefore, it took Jose 1 hour and 49 minutes to complete his homework altogether in 3 days.
Step 1: We need to minus the whole number and the fractions but first convert the mixed number into improper fractions.
Step 2: Find the LCD.
LCD: 16
Step 1: Convert the mixed number into improper fractions.
Step 2: Find the reciprocal of the divisor and change the sign into multiplication.
Step 3: Simplify the fraction.
