Choose the correct proportions.
cestrela7 [59]

Answer:

Options A, B and C are CORRECT PROPORTIONS

Step-by-step explanation:

Option A

3:5 = 6:10

The LHS must equal the RHS

3:5 is in it's lowest term.

6/10 will be in it's lowest term by dividing the numerator and denominator by 2.

6/10 = 3/5

Option B

3/6 and 5/10.

Diving 3/6 fractions by 3

= 1/2

Dividing 5/10 fraction by 5

= 1/2

Option C

Dividing 6/3 by 3 = 2

Dividing 10/5 by 5 = 2

Thats how you work through equivalent proportional fractions

I need help on figuring out the two ways.
Ymorist [56]
I believe the diagonals would be perpendicular. So if it's on a graph/coordinate plane the slopes would be opposite. And all the sides would be the same length/2 sets are parallel/same slope

Marcellus has a pitcher that contained 5/8 gallon limeade. Marcellus drank 1/4 gallon of the limeade, and Marcy drank 1/8 gallon
mash [69]

Answer:

2/5

Step-by-step explanation:

Given Marcellus drank 1/4 gallon of the limeade and Marcy drank 1/8 gallon of the limeade

Given that only 5/8 portion of the pitcher contains limeade

Total amount drunk = amount drunk by Marcellus + amount drunk by Marcy

Total amount drunk = \frac{1}{4} +\frac{1}{8} = \frac{3}{8}

The amount of Limeade remained = The amount initially - the amount drunk

The amount remained =  \frac{5}{8} -\frac{3}{8} = \frac{1}{4}

Fractional part = amount remained / amount initially = \frac{\frac{1}{4} }{\frac{5}{8} } = \frac{2}{5}
