Alicia receives 2/5 of a $120 gift, and Jason receives 1/3 of the gift. What is the ratio of Jason's share to Alicia's share? Ex
maria [59]

Answer:

5/6

Step-by-step explanation:

Step 1: Find Alicia's share of the gift. To do this, all you have to do is multiply 120 by 2/5, which is 40%. 120 * 40% (0.4) is 48. Alicia's share is $48.

Step 2: Find Jason's share of the gift. In this case, divide 120 by 3. 120/3 is 40. Jason's share is $40.

Step 3: Express the numbers as a fraction and simplify it. 40/48 is the common fraction. Find the GCF of 40 and 48. When you solve for it, the GCF is 8. Divide both the numerator and the denominator by 8. 40/8 is 5/ 48/8 is 6. There. 5/6 is our simplified fraction, which is the ratio.

Ipatiy [6.2K]
Use PEMDAS
Parenthesis
Exponents
Multiplication Division (Left to Right)
Addition Subtraction (Left to Right)
<em>First evaluate the operations inside of the brackets</em>
-8 + 2[5 + (-4 + 1)2] <em>evaluate (-4 +1) because it is surrounded by parenthesis</em>
-8 + 2[2 + (-3)2]) <em>multiply (-3)2
</em>-8 + 2[2 - 6] <em>subtract 2 - 6 because it is surrounded by the brackets (parenthesis)
</em>-8 + 2(-4) <em>multiply 2(-4)</em>
<em>-8 - 8
-16</em>
