My answer?

• Step 1: Select the fraction with 10 as the denominator

• Step2: Multiply both the numerator and denominator by ten (WHAT YOU DO TO THE TOP YOU DO TO THE BOTTOM)

• Step 3: The new fraction is now the fraction you use to add to your second fraction.

• Step 4: You ONLY add the numerators. Your denominator will ALWAYS be 100
