Divide the following quantities in the given ratios. a N2800 in the ratio 1:3
b 800 mm in the ratio 3:2
C 88 bananas in the ratio 6:5

see explanation

Step-by-step explanation:

(a)

sum the parts of the ratio, 1 + 3 = 4 parts

Divide the amount by 4 to find the value of 1 part of the ratio

2800 ÷ 4 = 700 , then

3 parts = 3 × 700 = 2100

2800 in the ratio 1 : 3 = 700 : 2100

(b)

3 + 2 = 5 parts , then

800 ÷ 5 = 160 ← value of 1 part of the ratio , then

3 parts = 3 × 160 = 480

2 parts = 2 × 160 = 320

800 mm in the ratio 3 : 2 = 480 mm : 320 mm

(c)

6 + 5 = 11 parts , then

88 ÷ 11 = 8 ← value of 1 part of the ratio , then

6 parts = 6 × 8 = 48

5 parts = 5 × 8 = 40

88 bananas in the ratio 6 : 5 = 48 : 40

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
