Answer:
D. 15×4/100×4 = 60/400
Step-by-step explanation:
First I figured out how many photos there are in total, which was by doing 60/.15, since only 15% of the total photos are in black and white. We can already cross out all possibilities that don't have the denominator 400, but we can go a step further by seeing which one is 60/400, or equal to 60/400, which is D. 15×4/100×4 = 60/400.
Answer:
1 5/12 lb
Step-by-step explanation:
This is a subtraction problem.
He started with 4 2/3 lb and used 3 1/4 lb, so you need to subtract 3 1/4 lb from 4 2/3 lb.
Notice that the fractions do not have the same denominator, so we need a common denominator and equivalent fractions.
We start with the
subtraction below
4 2/3
- 3 1/4
---------------
The least common denominator of 3 and 4 is 12. 12/3 = 4, and 12/4 = 3, so we get equivalent fractions with the common denominator 12.
We use the LCD to get
the subtraction below
4 8/12
- 3 3/12
----------------
Now we subtract the whole numbers and the fractions.
4 8/12
- 3 3/12
----------------
1 5/12
Answer: 1 5/12 lb
Answer:
The length is 7.50metres and the width is 5metres
Explanation:
Given the following
Length = 1.5Width
Perimeter = 25m
Required
Dimension of the room
Perimeter of the rectangular room = 2(L+W)
Since L = 1.5W
P = 2(1.5W+W)
P = 2(2.5W)
P = 5.0W
25 = 5W
W = 25/5
W = 5metres
Since L = 1.5W
L = 1.5*5
L = 7.5meters
The length is 7.50metres and the width is 5metres
11÷2.21=4.97
Rounded to the nearest tenth is 5.0
