Step-by-step explanation: To find how much of the candy bar they each have, we will have to add the fractions. To add unlike fractions such as 1/3 and 4/12, we first need to find a common denominator. The common denominator of 3 and 12 is simply the least common multiple of 3 and 12 which is 12. To get 12 in the denominator of 1/3, we multiply the numerator and denominator by 4 to get 4/12. Notice that our second fraction already has 12 in the denominator so we can now add these fractions.
+ = .
Notice that 8/12 can be reduced by dividing both the numerator and denominator by 4.
8 ÷ 4 = 2
12 ÷ 4 = 3
Therefore, Jackie and Steven have 2/3 of a Hershey bar.
(8-3)²-(5-2)² Follow the PEMDAS P-Parenthesis E-Exponents M/D-Multiplication/Division A/S-Addition/Subtraction clear the numerals in the parenthesis: (5)²-(3)² Now do the exponents: =25-9 =16 Its just: (5)²-(3)²
