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

Sagot :

Answer:

71/20 or 3 [tex]\frac{11}{20}[/tex]

Step-by-step explanation:

→ 9 [tex]\frac{3}{10}[/tex] = 9 * 10 + 3 / 10

9[tex]\frac{3}{10}[/tex] = 93/10

→ 5 [tex]\frac{3}{4}[/tex] = 5 * 4 + 3 / 4

5 [tex]\frac{3}{4}[/tex] = 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 [tex]\frac{11}{20}[/tex]
