Eileen makes her own granola using 1 3/4 cups of oats and 2/3 cup of puffed rice. How many cups of granola does she have?
barxatty [35]

Answer:

2 5/12 cups

Step-by-step explanation:

<u>First, turn 1 3/4  into improper fraction:</u>

1 3/4 = 7/4

<u>Next, Find LCG (least common multiple) of 3 and 4</u>

Multiples of 4: 4, 8, 12, 16, 20, 24

Multiples of 3: 3, 6, 9 , 12, 15, 18

<u>Multiply 7/4 by 3 and 2/3 by 4</u>

7/4 x 3 = 21/12

2/3 x 3 = 8/12

<u>Add both fractions</u>

21/12 + 8/12 = 29/12

<u>Reduce 29/12</u>

29/12 = 2 5/12

So Eileen has 2 5/12 cups of granola

Hope this helps ;)

% change = (new value - old value)/old valu x 100 = (1,045 - 950)/950 x 100 = 95/950 x 100 = 0.1 x 100 = 10%

Mrs Atkins is going to choose two students from her class to take part in a competition.
Schach [20]

Given:

Total number of girls in her class = 16

Total number of boys in her class = 14

To find:

The number of different ways of choosing one girl and one boy.

Solution:

We have,

Total number of girls = 16

Total number of boys = 14

So,

Total number of ways to select one girl from 16 girls = 16

Total number of ways to select one boy from 14 boys = 14

Now, number of different ways of choosing one girl and one boy is

16\times 14=224

Therefore, the required number of different ways is 224.

63-48=15
