Hoochie [10]

Answer:

2 11/12

Step-by-step explanation:

total amount fred used = 1/3 x 7 = 7/3

total amount Janice used = 1/4 x 7 = 7/4

total amount used =

7/3 + 7/4

(28 + 21) / 12 = 49 / 12 = 4 1/12

Amount left = 7 - 4 1/12 = 2 11/12

Compare adding unlike fractions and adding like fractions

muminat

Answer:

We just add numerators and rewrite denominator.

Adding unlike dominators:

We need to find the same denominators. You need to find the least common multiple (LCM) of the two denominators.

Step-by-step explanation:

You mean unlike denominators and like denominators.

Adding like dominators: We just add numerators and rewrite denominator :

Example : $\frac{1}{4} +\frac{2}{4}=\frac{1+2}{4} =\frac{3}{4}$

Adding unlike dominators:

We need to find the same denominators. You need to find the least common multiple (LCM) of the two denominators.

For example :

$\frac{1}{5}+\frac{3}{4}$

LCM for 5 and 4 is 20 : Now, divide by 5 and multiply by 1 for first fraction. 20 divide by 4 and multiply by 3 :

$\frac{1*4}{20} +\frac{3*5}{20}=\frac{4}{20} +\frac{15}{20}=\frac{19}{20}$

Find the value of y.

barxatty [35]

For this, since 4y - 7 and 2y - 1 are congruent, we can solve for y by setting them equal to each other.

$4y-7=2y-1$

Firstly, subtract 2y on both sides of the equation. $2y-7=-1$

Next, add 7 on both sides of the equation. $2y=6$

Finally, divide 2 on both sides of the equation, and your answer will be y = 3
