Answer 1

Answer: 7/4 and 1 3/4

Step-by-step explanation:

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(4, 4) = 4. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 4 × 4 = 16. In the following intermediate step, it cannot further simplify the fraction result by canceling.

In other words - seventeen quarters minus ten quarters = seven quarters.

Answer 2

C.
`\sf (7)/(4)`

D.
`\sf 1(3)/(4)`

Step-by-step explanation:

`\hookrightarrow \sf 4(1)/(4)-2(2)/(4)`

`\hookrightarrow \ \sf (17)/(4)-(10)/(4)`

`\hookrightarrow \sf (17-10)/(4)`

`\hookrightarrow \ \sf (7)/(4)`

`\hookrightarrow \ \sf 1(3)/(4)`

`\hookrightarrow 1.75`
