A relation are two sets of elements noted as input and output. Within relations, the input and the output have something in common.

A function is also about input and output but in a function, the input has nothing in common with the output.

Can someone please put 1 1/4 cups 0.4 L 950 mL and 0.7 gallons in greatest to least
Yuliya22 [10]

Answer:

0.7 gallons, 950 mL, 0.4 L, 1 1/4 cups

Step-by-step explanation:

First we need to convert the information given into one unit, in this case I will convert it into liters (L)

CUPS

1 cup is equal to 236.588 ml and is the same as .236 L using this information and knowing that 1 1/4 cup is the same as 1.25 cups we have that

x=\frac{1.25\times .236}{1}

x=.295 L

LITERS

0.4 L will stay the same

MILILITERS

1 liter is 1000 ml so 950 ml is the same as

x=\frac{950 \times 1}{1000}

x=.950 L

GALLONS

1 gallon is 3.78541 L so 0.7 gallons are

x=\frac{0.7 \times 3.785}{1}

x=2.649 L

arranging the data from greatest to least we have that 0.7 gallons, 950 mL, 0.4 L, 1 1/4 cups
