Answer:
28
Step-by-step explanation:
AB
4(7)=28
Step-by-step explanation:
2112 + 2212 + 2312 / 4 leaves no remainder, as already the individual numbers could be divided by 4 without remainder.
2113 = 2112 + 1
2213 = 2212 + 1
so, we get a remainder of +1 and +1 for these 2 numbers, so we get in total a remainder of +2.
Answer:
= 40%
Step-by-step explanation:
Original price = 100%
Discount = Op - Np = $49.99 - $29.99 = $20
If $49.99 = 100%
What about $20 = ?
= (20 x 100) ÷ 49.99
= 2000 ÷ 49.99
= 40.008
= 40%
Identity property!
Because the identity property for addition tells us that zero added to any number is the number itself. Zero is called the "additive identity." In this case, 0 is being added to 40.
It takes Jack 2 1/4 hours (or 9/4 hours) to complete a project. John takes 3/8 hours longer.
We need to add 9/4 + 3/8
First, make the denominators equivalent.
We can do this by multiplying 2/2 to 7/2 which makes the denominator 8 (since 3/8 is already 8)
9/4 x 2/2 = 28/8
(note that we can do this because 2/2 is 1 and multiplying a number by 1 doesn't change its value)
Add 28/8 + 3/8
28/8 + 3/8 = 31/8
31/8 hours is our final answer, as a mixed number it is 3 7/8 hours :)
