Answer:
therefore, 7/7 simplified to lowest terms is 1/1.
Step-by-step explanation:
Find the GCD (or HCF) of numerator and denominator
GCD of 7 and 7 is 7
Divide both the numerator and denominator by the GCD
7 ÷ 7
7 ÷ 7
Reduced fraction:
1
1
Therefore, 7/7 simplified to lowest terms is 1/1
Answer: $6000
Explanation:
1) Simple interest means that the interests are calcualted over the original amount borrowed and they are the same every year.
2) yearly interest = interest / number of years = $2400 / 10 = $240
3) the yearly interest equals the amount borrowed times the simple intereset rate:
=> $240 = A * 4%
=> $240 = A * 0.04
=> A = $240 / 0.04 = $6000
You can do the same in one step:
interest = A * simple interest rate * number of years
=> A = interest / [simple interest rate * number of years] = $2400 / [4% * 10]
A = $2400 / (0.04 * 10) = $2400 / 0.4 = $ 6000.
And that is the answer: he borrowed $6000
There are 30 rocks in Willy's collection.
Since the number of rocks in Willy's collection is x, the number in Billy's collection is (2 2/3)x or 8/3x.
x+(2 2/3)x = 110
(3 2/3)x=110
11/3x = 110
Dividing both sides by 11/3,
(11/3x)÷11/3 = 110÷11/3
x = 110÷11/3 = 110/1 ÷ 11/3 = 110/1 × 3/11 = 330/11 = 30
