2 division sign (2/3) + 3 division sign 4 division sign (4/5)=

why all the words?

2/3 + 3/4/5 = 2/3 + 3/20 = 49/60
2/3 + 3/(4/5) = 2/3 + 15/4 = 53/12

without parentheses, multiplication and division are done left to right, before any addition or subtraction.

um those arent any of the answer choices..

a) 1/5
b) 11/15
c) 47/60
d)3 13/30
e)12

you are right; I misread the words. Here is what you wrote, using only math symbols:

2/(2/3) + 3/4/(4/5)

Now start inserting parentheses until it means what you think it should. If you use wolframalpha.com, it will show what your entered text really means:

well that is what the problem said i just dont know how to put divison signs on the mac. So i put (division signs) that meant actual division signs

To evaluate the expression: 2 ÷ (2/3) + 3 ÷ 4 ÷ (4/5), we follow the order of operations (also known as PEMDAS/BODMAS) which states that we should perform calculations in the following order: parentheses, exponents, multiplication/division (from left to right), and addition/subtraction (from left to right).

Let's break down the expression step by step:

Step 1: Evaluate 2 ÷ (2/3)
To divide by a fraction, we multiply by its reciprocal. The reciprocal of (2/3) is (3/2). So, we have:
2 ÷ (2/3) = 2 × (3/2) = (2×3) / 2 = 6/2 = 3

Step 2: Evaluate 3 ÷ 4 ÷ (4/5)
Again, to divide by a fraction, we multiply by its reciprocal. The reciprocal of (4/5) is (5/4). So, we have:
3 ÷ 4 ÷ (4/5) = 3 × (1/4) × (5/4) = (3 × 1 × 5) / (4 × 4) = 15/16

Step 3: Add the results from Step 1 and Step 2
3 + 15/16 = 48/16 + 15/16 = 63/16

Therefore, the expression 2 ÷ (2/3) + 3 ÷ 4 ÷ (4/5) equals 63/16.
