How do you convert a mixed fraction to an improper fraction ?
maks197457 [2]

Answer:

see the explanation

Step-by-step explanation:

we know that

A mixed number is equal to sum a integer plus a fraction less than 1. The result is a fraction where the numerator will be always greater than the denominator (This fraction is called an improper fraction)

Example

a\frac{b}{c} ----> a mixed number

a is a integer

b/c < 1

so

a\frac{b}{c}=a+\frac{b}{c}

Adds the integer plus the fraction

\frac{ac+b}{c} ---> an improper fraction

\frac{ac+b}{c} > 1

Use the digits 1,2,3 and 4 once each to get the largest answer possible
sukhopar [10]

Answer:

4,321

Step-by-step explanation:

This is the answer because:

1) We know that if the number has to be big therefore, we have to put 4 in the thousands place because 4 is bigger than 3, 2, and 1

2) Next, 3 is the other biggest number, for that reason 3 is in the hundreds place

3) Then, 2 is the other bigger number; therefore, the tens place is 2

4) Finally, the last number remaining is 1, which is in the ones place

Therefore, the answer is 4,321

Hope this helps!
