12/8/4+7/2+12=?
BY THE WAY THIS IS 7TH GRADE MATH
not clear what 12/8/4 means
is it (12/8)÷4 or
is it 12÷(12/8) ?
first:
(12/8)÷4
= (3/2)÷4
= (3/2)x(1/4) = 3/8
second:
12÷(12/8)
= 12÷(3/2)
= 12x(2/3) = 8
... of course you would then add 7/2 + 12 to whichever is the right interpretation.
To solve this arithmetic expression, we follow the order of operations, which is often abbreviated as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) or BODMAS (Brackets, Orders, Division and Multiplication, Addition and Subtraction).
Let's break down the expression step by step:
First, we need to simplify the addition of fractions. To add fractions, we need a common denominator. In this case, we can find the least common multiple (LCM) of 8 and 2, which is 8.
Now, let's rewrite the expression with a common denominator:
12/8/4 + 7/2 + 12
Next, we can add the fractions by adding the numerators (the numbers on the top) and keeping the same denominator:
(12 + 7)/8 + 12
Simplifying further:
19/8 + 12
To add these two fractions, we need a common denominator, which is 8.
Now, we can rewrite the expression with a common denominator:
19/8 + 12/1
To add fractions, the denominators must be the same. So we can rewrite 12/1 as 96/8:
19/8 + 96/8
Finally, we can add the fractions:
(19 + 96)/8
115/8
So, the sum of 12/8/4 + 7/2 + 12 is 115/8.
