He shaded 1/3 of one rectangle and 1/4 of other rectangle. What is the least number of parts into which both rectangles could be divided?

Answers


Rectangle 1: 1/3 shaded

Rectangle 2: 1/4 shaded

First you have to look through each denominators multiples to find the lowest common denominator (LCD).

Multiples of 3: 3, 6, 9, 12, 15

Multiples of 4: 4, 8, 12, 16, 20

As you can see, both numbers are multiples of 12.

Rectangle 1: 1/3 shaded= 4/12 shaded

Rectangle 2: 1/4 shaded= 3/12 shaded

I made equivalent fractions by multiplying both the numerator and the denominator by the same number.

The least number of parts which both rectangles can be divided is 12.

Consider the following set of equations:Equation A: y = 2x + 4
Equation B: y = 3x + 1

Which of the following is a step that can be used to find the solution to the set of equations?

2x = 3x + 4
2x + 4 = 3x
2x + 1 = 3x + 4

Step-by-step explanation:

10 1/2 cups of flour are needed to make 3 loaves of bread. How many cups are needed for 12?

Answers

Answer:

42 cups of flour

Step-by-step explanation:

12 is 4 times more than 3 (3 × 4 = 12), so we know that we need 4 times 10 1/2 (equal to 10.5) cups of flour.

All we need to do for this is do 10.5 × 4 = x and solve for x.

10.5 × 4 = 42 cups of flour

Which fraction is not equivalent to 16/24 A. 2/3 B. 5/8 C. 32/48 D. 4/6

Answers

b) 5/8
because:
2/3 x 8 = 16/24
32/48 divided by 2 = 16/24
4/6 x 4 = 16/24
so b) 5/8 it is


5/8 because 
If you divide 16 by 8 then you get 2 and if you divide 24 by 8 you get 3 this equals=2/3
32/48- If you multiply 16 by 2 you get 32, if you multiply 24 by 2 you get 48 which gives you an answer to 32/48
4/6- If you divide 16 by 4 you get an answer of 4, if you divide 24 by 4 you get an answer of 6, which gives you an answer of 4/6
