Answer:

The hierarchy is starting by the parenthesis, followed by any multiplications or divisions and ultimately the additions and subtractions.

Step-by-step explanation:

First operation

1. (1/5+1/2)=(2/10+5/10)= 7/10

2. (7/10)^2= 49/100

4. (49/100) + (3/50)= (49/100 + 6/100) = 55/100

Second operation

We start by the numerator

1. (18 - 4^2 +2) = 18 - 16 +2 = 4

2. 4*2 = 8

Following with denominator

1. 1/4*12= 1/48

When we divide a number by a fraction we have to make use of the following rule (a/b)/(c/d)=(a*d)/(b*c)

Hence: (8)/(1/48) = 8*48 / 1 = 8*48 =384

seraphim [82]

Answer:

Step-by-step explanation:

<em>Step 1: Determine quantity per liquid</em>

liquid 1=7/8 cup

liquid 2=9/10 cup

<em>Step 2: Derive expression to calculate total amount of mixture</em>

The expression below can be derived;

T=a+b

where;

T=total amount of mixture

a=total amount of liquid 1

b=total amount of liquid 2

In our case;

a=7/8 cup

b=9/10 cup

replacing;

T=(7/8)+(9/10)=1 31/40 cups

The total amount of mixture=1 31/40 cups
