A family spends 1/10 of its annual income for housing, 1/4 for food and clothes, 1/5 for general expenses, and 2/15 for entertainment. What fractional part of their income is spent on these items altogether? A. 1/7
B. 6/41
C. 41/60
D. 11/12

Answers

Answer 1

Answer: Add all the fractions together:
to do this find the lcd:
which is 60
1/10 = 6/60
1/4= 15/60
1/5= 12/60
2/15= 8/60
add them together
(6+15+12+8)/60
41/60 or C is the answer

Answer 2

Answer: C is the right answer

Answer:

g = 6

Step-by-step explanation:

3.8g + 8 = 1.8g + 20

Subtract 1.8g from both sides;

2g + 8 = 20

Subtract 8 from both sides;

2g = 12

Divide both sides by 2;

g = 6

You can check if the value of g is correct by plugging in the value of g to the equation. If your check does not it doesn't mean your answer is not correct because sometimes it can be a no solution equation which means that there is no solution to the equation.

Check:

3.8(6) + 8 = 1.8(6) + 20

22.8 + 8 = 10.8 + 20

30.8 = 30.8

It means its correct

At a grocery store, the price of 3 cans of soup is $6.90. at this rate, how much would 10 cans of soup cost

Answers

Answer:

$23

Step-by-step explanation:

At a grocery store 3 cans of soup cost $6.90

3 cans = 6.90

1 can= 6.90/3

1 can = $2.3

Therefore the cost of 10 cans can be calculated as follows

1 can= $2.3

10 cans= 10×2.3

= $23

Hence 10 cans will cost $23
