Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

7/8y + 1/2 = 1 1/5

<u>Step 2: Solve for </u><em><u>y</u></em>

  1. Convert to improper fraction:                                                                          7/8y + 1/2 = 6/5
  2. [Subtraction Property of Equality] Subtract 1/2 on both sides:                       7/8y = 7/10
  3. [Division Property of Equality] Divide 7/8 on both sides:                              y = 4/5

Your teacher writes the fact below on the board.Using only mental math, will the answer be less than or greater than 5? How do y
Levart [38]

Answer:

Less than 5

Step-by-step explanation:

The eason behind the answer being less than 5 is because if you multiply something by a fraction that is less than a whole number, then you will get less than the original number you multiplied the fraction with.

Hope this helps :)

Help me with number three plzzzz i took a picrure below
kvasek [131]
All you have to do to solve this problem is to put it into fraction form: if for every $4 Jo makes, Leila makes $3, then the fraction would be 3/4.

To solve this divide 60 by 4 to get 15 and then multiply 15 by 3 to get Leila's pay. 15*3=45

Check it by putting it into simplest form as a fraction to see if it checks:

45/60=3/4 and 3/4=3/4 so therefore Leila makes $45 in profit
