Answer 1

1. 8 gallons

2. 8 feet

3. 32

4.

5. half an hour/ 30 min

Explanation:

1.

$milk \: needed \: by \: 65 \: kids = 4gal$

$130 \div 65 = 2$

$2 \times 4gal \: = 8gal \:$

$\therefore \: milk \: needed \: by \: 130 \: kids \: \: = 8gal$

2.

$total \: length \: of \: wood \: = 12ft$

$ratio \: = \: 1 \ratio2$

$total \: number \: of \: parts = 1 + 2 = 3$

$\: 12 \div 3 = 4$

$1 = 1 \times 4 \\ = 4$

$2 = 2 \times 4 \\ = 8$

$both \: the \: lengths = 4 \ratio8$

$bigger \: length = 8ft$

3.

$no. \: of \: teachers \: for \: 235 \: students = 4$

$no. \: of \: teachers \: for \: 1880 \: students = \frac{1880}{235} \times 4$

$= \frac{7520}{235} = 32$

$\therefore \: 32 \: teachers \: are \: required \:for \: 1880 \: students$
