Question

simplify 9-(7-8÷4) ​

Answer 1

$\tt \huge \green{answer}$

$\sf \implies \: 9 - (7 - \frac{8}{4} )$

$\sf \implies \: 9 - ( \frac{28 - 8}{4} ) \\ \\ \sf \implies9 - ( \frac{20}{4} ) \\ \\ \sf \implies9 - (5) \\ \\ \sf \implies9 - 5 \\ \\ \sf \implies4$

Answer 2

Answer:

72

31

=0.43056

Step-by-step explanation:

1. Simplify 4/9

2. 7/8 - 4/9

3. Simplify 7/8

4. Equation at the end of step 7/8 - 4/9

Calculating the Least Common Multiple;. Find the Least Common Multiple. The left denominator is : 8

The right denominator is : 9.... Therefore, Common Multiple: 72

5.Calculating Multipliers : Calculate multipliers for the two fractions.

Denote the Least Common Multiple by L.C.M

Denote the Left Multiplier by Left_M

Denote the Right Multiplier by Right_M

Denote the Left Deniminator by L_Deno

Denote the Right Multiplier by R_Deno

Left_M = L.C.M / L_Deno = 9

Right_M = L.C.M / R_Deno = 8

6. Making Equivalent Fractions : Rewrite the two fractions into equivalent fractions.

Two fractions are called equivalent if they have the same numeric value.

L. Mult. • L. Num. = 7 • 9

———————— ———

L.C.M 72

R. Mult. • R. Num. = 4 • 8

————————— ————

L.C.M 72

7. Adding fractions that have a common denominator :

7 • 9 - (4 • 8) = 31

——————— ——

72 7

Final Score = 31

---- = 0.43056
