Question

9 3/10 - 5 3/4 as a mixed number in simplest form

Answer 1

Answer:

3 1/20

Step-by-step explanation:

First, we will convert the mixed numbers into improper fractions...

9 3/10 (9*10=90+3=93) so the improper fraction is 93/10

5 3/4 (5*4=20+3=23) therefore the improper fraction is 23/4

We then want to make the denominator the same...

93/10 (*4) = 372/40

23/4 (*10) = 230/40

We then put it into the question...

372/40 - 230/40 = 142/40

Lastly, we now need to turn this into a mixed number...

142/40=3.55 so the answer is 3 2/40

3 2/40 in it's simplest form is 3 1/20

Hope this helps!

Answer 2

Answer:

71/20 or 3 $\frac{11}{20}$

Step-by-step explanation:

→ 9 $\frac{3}{10}$ = 9 * 10 + 3 / 10

9$\frac{3}{10}$ = 93/10

→ 5 $\frac{3}{4}$ = 5 * 4 + 3 / 4

5 $\frac{3}{4}$ = 23/4

Making the denominators alike;

93 * 4/ 10 * 4 = 372/40

23 * 10 / 4 * 10 = 230/40

93/10 - 23/4 = 372/40 - 230/40

= 142/40

= 71 / 20 (simplifying by dividing both by 2)  OR  3 $\frac{11}{20}$
