Answer:
50 newspapers
Step-by-step explanation:
100 (total amount of newspapers) - 25 (amount Edward already sold) = 75 (amount of newspapers left)
75 (amount of newspapers left) ÷ 3 (Edward and his 2 friends) = 25 (equal amount each person delivered)
25 (amount Edward already sold) + 25 (amount Edward sold after his friends helped him) = 50 (amount of newspapers Edward sold in total)
3.25 would be 3 1/4 because,
Step 1: You would rewrite the decimal number as a fraction with 1 in the denominator. So, 3.25 = 3.24/1
Step 2: Multiply it by 1 to eliminate 2 decimals places, so multiply the top and bottom by 10^2 = 100
3.25/1 x 100/100 = 325/100
Step 3: Now you find the greatest common factor, also known as GCF, of 325 and 100 if it exits then you reduce the fraction by dividing both numerator and denominator by it. GCF = 25
3.25/100 divided by 25/25 = 13/4
Now you would simplify it to make a proper fraction getting your answer
3 1/4
Does that make sense?
Answer:
42*3=126
28*5=140
the GCD of 126=2*3*3*7
the GCD of 140=2*2*5*7
2*7
GCD=14
Step-by-step explanation:
To complete the equation and tell which property you used.
(3×10)×8=___(10×8)
The property of basic operations that was used here is the:
1. Associative property of
multiplication where you can group or cluster certain values or numbers in an
equation and still yield the same product.
The missing value would be 3. Hence,
2. (3 × 10) × 8 = 3 (10 × 8)
Observe the parenthesis which has only moved from starting with three to
the value of ten.
