(mark as brainlist answer)

According to the given condition is the question :

Two numbers a and b are such that the sum of 5% of a and 4% of b is two-third of the sum of 6% of a and 8% of b

⇒ (5% of a) + (4% of b) = (2/3) × [(6% of a) + (8% of b)

⇒ 0.05a + 0.04b = 2/3 × (0.06a + 0.08b)

⇒ 0.15a + 0.12b = 0.12a + 0.16b

⇒ 0.03a = 0.04b

⇒ a/b = 4/3

⇒ a : b = 4 : 3

r-ruslan [8.4K]

Answer:

If 2/3 ton of gravel covers 3/4 of a driveway, you need to divide 2/3 divided by 3 to find how much is needed for 1/4 of the driveway. So first step:

1. 2/3 divided by 3 = 2/3 * 1/3. So 2/9.

2. Add 2/3 plus 2/9= 8/9 ton of gravel to cover the whole driveway.

Courtney adds 2 dimes,3 quarters,and 6 nickels into a money jar. courtney the takes out 2 quarters and 5 dimes the next day.writ

Maslowich

Write an expression for the amount she added:

Dimes: 2(0.10)

Quarters: 3(0.25)

Nickels: 6(0.05)

Now write an expression for what she took out:

Quarters: 2(0.25)

Dimes: 5(0.10)

Now combine them:

2(0.10) + 3(0.25) + 6(0.05) - 2(0.25) - 5(0.10)

Simplify:

0.20 + 0.75 + 0.30 - 0.50 - 0.50

1.25 - 1.00 = 0.25 increase.
