Answer:

=2 7/12 is needed on sunday

Step-by-step explanation:

Friday + Saturday + Sunday = total time studying

1 1/4 + 2 2/3 + sunday = 6 1/2

Get a common denominator of 12

1/4*3/3 =3/12

2/3 *4/4 =8/12

1/2 *6/6=6/12

1 3/12   + 2 8/12 + sunday = 6 6/12

Combine terms

3 11/12 + sunday = 6 6/12

Subtract 3 11/12 from each side

3 11/12  - 3 11/12 + sunday = 6 6/12 - 3 11/12

sunday =  6 6/12 - 3 11/12

Borrow 1 from 6 in the form of 12/12

sunday =  5 + 12/12+ 6/12 - 3 11/12

            = 5 18/12 - 3 11/12

             =2 7/12

Write two different expressions to represent the sale price of a fishing pole, f, after a 20% discount.
Rom4ik [11]

Answer:

When we have a discount of X% of the original price, the new price is calculated as:

New price = (original price) - (original price)*(X%/100%)

In our case, let's define:

P = original price of the fishing pole

f = price of the fishing pole after the discount

X% = 20%

Then the equation for the price of the fishing pole is:

f = P - P*(20%/100%) = P - P*0.2 = P*(1 - 0.2) = P*0.8

f = 0.8*P

This means that the price after the discount is 0.8 times the original price.
