What would the answer be but with work showing with it ?? -<br> 3/4-2/5
kenny6666 [7]
Get a common denominator.

3/4.. multiply the numerator and denominator by 5.
3/4 × 5 = 15/20
2/5.. multiply the numerator and denominator by 4.
2/5 × 4 = 8/20
subtract
15/20 - 8/20 = 7/20
the answer is 7/20 because you cannot simplify it.

ankoles [38]

Answer:

In 5 weeks they will have the same amount.

Step-by-step explanation:

1. You have that Tyronne has $60, she gets $5 each week and also gets an additional $10 each week. She saves her money. Therefore, you can write the following expression:

60+5x+10x\\60+15x

Where x is the number of weeks.

2. Her sister has $135, she gets $5 each week and also gets an additional $10 each week, but she spends this money. Therefore:

135+5x+10x-5x-10x\\135

3. If this amounts of money will be equal, you have:

60+15x=135\\15x=75\\x=5

4. Therefore, in 5 weeks they will have the same amount.
