d. 5 4/6

2.
a.) 5/2
b.) 31/8
c.) 23/3
d.) 44/5

For the first section, divide the bottom number into the top number. The lowest whole number you get will be the big number on the outside. The remaining numbers will be in the numerator. For example, in a for the first section, I divided 4 into 5. Four only goes into five once equally, so the big number would be one. To reach five, just add one more to the numerator to get 1 1/4.

For the second section, just multiply the big number into the denominator, then add the numerator. For example, in a of the second section, I multiplied 2 times 2, giving me 4. The numerator is 1, so adding it to 4 gives me 5, making the answer 5/2. Notice how the denominator always stays the same.

Step-by-step explanation:

A new theater is being built for the city ballet. The balcony has 100 seats. The floor has 20 rows with x seats in each row. The number of people in the theater must be under 400 to meet fire safety regulations.
The new theater must have more than 15 seats in each row on the floor to meet fire safety regulations.

The new theater must have fewer than 15 seats in each row on the floor to meet fire safety regulations.

The new theater must have more than 20 seats in each row on the floor to meet fire safety regulations.

The new theater must have fewer than 20 seats in each row on the floor to meet fire safety regulations.

Answers

Answer:

The new theater must have fewer than 15 seats in each row on the floor to meet fire safety regulations.

Step-by-step explanation:

The equation/formula

is  100+20x ≤ 400

1. Subtract 100 from both sides

-100+20x≤ 400-100

-->  20x≤300

2. Divide 20 by x and 300

20/20x≤ 300/20

--> x≤15

So...

The new theater must have fewer than 15 seats in each row on the floor to meet fire safety regulations.

1 3/4 pounds of pancake mix. Jada used 7/8 pound for a recipe. What fraction of the pancake mix in the box did she use?

Answers

Answer:

7/8

Step-by-step explanation:

If you turn 1 3/4 back into a simplified fraction it is 7/4. But the denominators need to be the same, so multiply the bottom number 2 and the top number by 2. That gives you 14/8. If she used 7/8 of it, then you just do 14/8 - 7/8 which gives you 7/8.
