Karolina [17]

Answer:

Number of Cups = 19

Step-by-step explanation:

Given

Size of Soup = 6.5 litres

SIze of cup = 330 ml

Required

Number of Cups.

First, it'll be assumed that the size of cups are uniform (the same).

The number of cups needed is calculated by dividing the size of soup by the size of the cup;

Number of Cup = Size of Soup/Size of Cup

Number of Cup = 6.5 litres/ 330 ml

Convert units;

1 litres = 1000 ml

So,

6.5 litres = 6.5 * 1,000 ml

6.5 litres = 6,500 ml

So,

Number of Cups = 6500 ml/330 ml

Number of Cups = 19.696969697

From the solution above, Naveed will definitely be able to serve 19 cups. The remaining fractional part won't fill a cup;

Hence, Number of Cups = 19

Tricky but not crazy hard. You could use th x/y method where you turn it into a cross multiplication fiasco.

or you can try your guesses through what ever equals 1/2 when you add one to the denominator. the answer you are looking for is 2/3

2/3 + 1 for the numerator = 1.

2/3 + 1 for the denominator = 1/2.

PLEASE HELP ME 3X+1/14=2X/8 WHAT IS X? EXPLAIN HOW YOU GOT THE ANSWER

balandron [24]

Cross-multiply so that 8(3x + 1) = 14(2x)

Distribute the 8 and 14 into the parentheses:
24x + 8 = 28x

Subtract 24x from both sides:
8 = 4x

Divide both sides by 4:
x = 2
