a. $\frac{11}{12}$

b. $\frac{39}{20}$

c. $\frac{20}{21}$

Step-by-step explanation:

Step 1; First, we convert the given fractions into improper ones. To do this, we multiply the whole number with the denominator of the fraction and add with it the same fraction's numerator whereas the denominator remains unchanged. To convert the fraction

3 $\frac{1}{4}$ = (3 × 4) + 1 / 4 = $\frac{13}{4}$ ,

2 $\frac{1}{3}$ = (2 × 3) + 1 / 3 = $\frac{7}{3}$ ,

6 $\frac{1}{5}$ = (6 × 5) + 1 / 5 = $\frac{31}{5}$ ,

4 $\frac{1}{4}$ = (4 × 4) + 1 / 4 = $\frac{17}{4}$ ,

5 $\frac{2}{7}$ = (5 × 7) + 2 / 7 = $\frac{37}{7}$ ,

4 $\frac{1}{3}$ = (4 × 3) + 1 / 3 = $\frac{13}{3}$ .

Step 2; Now we subtract, using LCM to arrive at the answer

3 $\frac{1}{4}$ - 2 $\frac{1}{3}$ = $\frac{13}{4}$ - $\frac{7}{3}$ = $\frac{39-28}{12}$ = $\frac{11}{12}$ ,

6 $\frac{1}{5}$ - 4 $\frac{1}{4}$ = $\frac{31}{5}$ - $\frac{17}{4}$ = $\frac{124-85}{20}$ = $\frac{39}{20}$ ,

5 $\frac{2}{7}$ - 4 $\frac{1}{3}$ = $\frac{37}{7}$ - $\frac{13}{3}$ = $\frac{111-91}{21}$ = $\frac{20}{21}$ .

by selling a mobile set of rupees 4800 Ramesh gains 25% how much will have we gained by selling it at rupees 4080

Crank

Answer:

240

Step-by-step explanation:

Gain=25%

Gain=selling price - cost price

Gain = ((selling price - cost price )× 100)/ cost price

25c=(4800-c)100

25c=480000-100c

125c=480000

cost price = 3840

second statement

The selling price was 4080

Cost price 3840

therefore

Gain=selling price - cost price

Gain = 4080-3840

=240

Please help with this math question

Sergio039 [100]

Answer:

t = 16/3

Step-by-step explanation:

4/3 : 7= 3t/4 :21

4/3 x 21 = 7 x 3t/4

28 = 21t/4

112 = 21t

t = 112/21 → t = 16/3
