Answer:

Part A: x÷3=$499

Part B: $1497

Step-by-step explanation:

A: Because to find a fraction of somthing we have to divide, so in this case we divided the original price by 3 to get $499.

B:To find the original price we have to multiply the one third of it ($499) by 3 to get the original amount.

Marcus needs 3 1/10 m of blue fabric and 1 1/5 m of yellow fabric to make his costume. How much more blue fabric than yellow fab
Kamila [148]

Answer:

1\frac{9}{10}\ m

Step-by-step explanation:

we know that

To find out how much more blue fabric than yellow fabric does Marcus need, subtract the quantity of yellow fabric from the quantity of blue fabric

step 1

Convert mixed number to an improper fraction

3\frac{1}{10}\ m=\frac{3*10+1}{10}=\frac{31}{10}\ m

1\frac{1}{5}\ m=\frac{1*5+1}{5}=\frac{6}{5}\ m

step 2

Subtract the numbers

\frac{31}{10}-\frac{6}{5}=\frac{31}{10}-\frac{12}{10}=\frac{19}{10}\ m

Convert to mixed number

\frac{19}{10}\ m=\frac{10}{10}+\frac{9}{10}=1\frac{9}{10}\ m

A pizzeria uses a 3-pound bag of cheese to make 8 pizzas. Use the given ratio to compute the number of pizzas the pizzeria can m
Arada [10]

Answer:

18 pounds = 48 pizzas

18 pounds = 48 pizzas 22.5 pounds = 60 pizzas

18 pounds = 48 pizzas 22.5 pounds = 60 pizzas 27 pounds = 72 pizzas

Step-by-step explanation:

1) because they are ratios you multiply 18 and 8 (18 × 8 = 144) then you divide 144 by 3 (144÷3 =48)

2) now you do the same thing multiply 22.5 and 48 (22.5 × 48= 1,080) and divide 1,080 by 18 (1,080 ÷ 18= 60)

3) multiply 27 times 60 (27 × 60= 1,620) now divide 1,620 by 22.5 (1,620 ÷ 22.5= 72)

slava [35]

Answer:

M = 42

Step-by-step explanation:

Ooo..I'm actually good at these!!

So its simple...All you do is take the equation and divide both sides by 4.5

When we divide, we get m alone.

4.5m = 189

/4.5       /4.5

m = 42

Hope this helps!! Can I have brainliest please?!?
