Question

Pls help me in this question 4 3/4 x 2 1/8

Answer 1

hope this will help you

`= 4 (3)/(4) * 2 (1)/(8) \\ = (4 * 4 + 3)/(4) * (8 * 2 + 1)/(8) \\ = (19)/(4) * (17)/(8) \\ = (323)/(32) \\`

Answer 2

Given expression:

`\sf 4 (3)/(4) * 3 (1)/(8)`

Convert the mixed numbers into improper fractions by multiplying the whole number by the denominator of the fraction and adding it to the numerator:

`\sf \implies (4 * 4 +3)/(4) * (2 * 8+1)/(8)`

`\sf \implies (16 +3)/(4) * (16+1)/(8)`

`\sf \implies (19)/(4) * (17)/(8)`

Multiply the denominators and the numerators:

`\sf \implies (19 * 17)/(4 * 8)`

`\implies \sf (323)/(32)`

Convert back into a mixed number:

`\implies \sf (320+3)/(32)`

`\implies \sf (320)/(32)+(3)/(32)`

`\sf \implies 10 (3)/(32)`
