6 3/4 - 2 3/20

Answers

Answer:

4 3/5

Step-by-step explanation:

Change 6 3/4 into 6 15/20

Subtract 6 15/20 by 2 3/20 = 4 12/20

Simplify by dividing both numerator and denominator by 4.  Answer is 4 3/5

Answer:

23/5

Step-by-step explanation:

6 3/4=27/4

2 3/20=43/20

27/4-43/20=135/20-43/20=92/20=23/5

Liang went to the bookstore. he spent 1/3 of his ,money on a pen and 4/7 of it on books. what fraction of his money did he have left?

Answers

Convert into like fractions --> 
1/3 = 7/21 4/7 = 12/21
7+12 = 19
19/21 is spent therefore he has 2/21 left

The fraction of the amount Liang has left is (2)/(21)

  • Let X = Amount spent on a pen; X = (1)/(3)
  • Let Y = Amount spent on books; Y = (4)/(7)
  • Let M = Amount of money Liang has got; M =?
  • Let L = Amount of money Liang will have left; L = ?

Further Explanation

To derive L (amount of money Liang will have left), add X (amount spent on a pen) and Y (amount spent on books) together, then the derived value be subtracted from M (fraction of total amount Liang has got) i.e.: M – (X + Y)

Therefore, L = M – (X + Y)

Deriving (X + Y)

= X + Y

= (1)/(3) + (4)/(7)

= (1 x 7) + (3 x 4) / 21

= (7) + (12) / 21

= 7 + 12 / 21

= (19)/(21)

X + Y = (19)/(21)

Since the lowest common denominator of the fraction of X and Y = 21, then the fraction of M = (21)/(21)

Thus, M = (21)/(21)

Recall, L = M – (X + Y)

Thus,

L = (21)/(21) – (19)/(21)

L = (1 x 21) – (1 x 19) / 21

L = (21) – (19) /21

L = 21 – 19 /21

L = (2)/(21)

Hence, the amount Liang will have left is (2)/(21)

Divide 25kg in a ratio of 2:3:5

Answers

The required answer is 25 kg in the ratio 2 : 3 : 5 = 5 : 7.5 : 12.5.

What is Ratio?

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

We have to divide 25 kg into the ratio 2 : 3 : 5

The ratio is given in the question

⇒ 2:3​:5

We can see that the sum of the parts of the given ratio as

⇒ 2 + 3 + 5 = 10 parts

Divide 25 by 10 to determine the value of one part of the ratio

So the value of 1st part of the ratio

⇒ 25 ÷ 10 = 2.5

Now, 2nd parts = 2 × 2.5 = 5

And, 3rd parts = 3 × 2.5= 7.5

And, 4th parts = 5 × 2.5= 12.5

So, 25 in the ratio 2 : 3 : 5 = 5 : 7.5 : 12.5

Therefore, the required answer is 25 kg in the ratio 2 : 3 : 5 = 5 : 7.5 : 12.5.

2 + 3 + 5 = 10

25 ÷ 10 = 2.5

2.5 × 2 = 5
2.5 × 3 = 7.5
2.5 × 5 = 12.5

5 : 7.5 : 12.5
