Answer:
8 4/15
Step-by-step explanation:
Rewriting our equation with parts separated
= 5 + 2/3 + 2 + 3/5
Solving the whole number parts
5 + 2 = 7
Solving the fraction parts
2/3 + 3/5 = ?
Find the LCD of 2/3 and 3/5 and rewrite to solve with the equivalent fractions.
LCD = 15
10/15 + 9/15 = 19/15
Simplifying the fraction part, 19/15,
19/15 = 1 4/15
Combining the whole and fraction parts
7 + 1 + 4/15 = 8 4/15
Set The Numbers On The Side Equal To The Equation. Use Inverse Operation And Divide Since The X Is Used In Multiplication.
