Answer:
1a. 58/99
1b. 53/90
1c. 29/50
Step-by-step explanation:
let's start with the easiest one
1.(c)
0.58 = 58/100 = 29/50
that is the simplest possible form, as 29 is a prime number and not a factor of 50.
1.(a)
0.585858585858... = 58×0.0101010101010101...
now, we know that 1/"double digit" (like 1/22) mostly produces a repeating pattern with a period length of 2 after the decimal point.
and we find
1/99 = 0.01010101010101...
so, our solution is
58 × 1/99 = 58/99
that is the simplest possible form, as 58 and 99 do not share any factors.
1.(b)
0.5888888888888... = 0.5 + 0.0888888888888... =
= 0.5 + 8×0.01111111111111... = 0.5 + 8×1/10 × 0.1111111111...
we know how to create 0.11111111111... :
1/9 = 0.111111111111111...
so, our solution is
0.5 + 8 × 1/10 × 1/9 = 0.5 + 8/90 = 5/10 + 8/90 =
= 45/90 + 8/90 = 53/90
this is the simplest possible form, as 53 is already a prime number and not a factor of 90.
Answer: Brian should ask a price of £520 for the guitar.
Step-by-step explanation:
Given : Making cost of guitar= £325
Mark up percentage = 60%=0.60 [we divide percentage by 100 to convert into decimal]
Now , the price should be asked by Brian May for the guitar would be :
(Making cost of guitar) + 60% of (Making cost of guitar)
=(Making cost of guitar) + (0.60) x (Making cost of guitar)
= (Making cost of guitar) x (1+0.60) [By distributive property]
= (£325) x (1.60)
= £520
Hence, Brian should ask a price of £520 for the guitar.
We know because they are both 7, but 7.031 has 031. 7.03 only has .03, if that makes sense
Answer: 121
<u>Multiply</u>
20%×605=121
Note: When finding the percent of a number multiply the percent times the number.
