Answer:
Step-by-step explanation:
Convert the given fractions into like fractions.
To do so, Take the L.C.M ( Least Common Multiple ) of 3 and 4.
To find out the L.C.M of given numbers,
First of all, find the prime factors of each numbers.
3 = 3 × 1
4 = 2 × 2 × 1
Take out the common prime factor i.e 1
Also take out the other remaining prime factors i.e 2 , 2 and 3
Now, multiply those all prime factors and obtain L.C.M
= 1 × 2 × 2 × 3 = 12
L.C.M of 3 and 4 = 12
Add the numbers : 20 and 21
Convert the improper fraction into mixed fraction
Remember : While performing the addition or subtraction of unlike fractions, you have to express the given fractions into equivalent fractions of common denominator and add or subtract as we do with like fractions. Thus , obtained fractions should be reduced into lowest terms if there are any common on numerator and denominator. But in case of improper fraction, it needs to be deduced on mixed fraction.

Answer:
she would pay 97.2 in tax
would pay with tax included 24397.2
she can buy the car with cash
Step-by-step explanation:
24300
24300 times 0.4 then do
9720 divided by 100
97.2
she would pay 97.2 in tax
24300 + 97.2 is 24397.2
would pay with tax included 24397.2
she can buy the car with cash
Answer:
0.375 is the correct answer
Lovely algebra.
Given that Jack scored a number that is 17 more than Yazid's number,
1) Jack = x + 17
So we know yazid has 17 less than jack so we minus 17 from jack's equation. (x + 17) - 17 = x
2) Yazid = x
It is also given that Susan scored twice of Yazid's score therefore we can multiply Yazid's equation.
3) Susan = 2(x)
= 2x
Finally, it tells us that everyone's score added up is 161 therefore we can write the whole equation like this:
4) (x+17)+(x)+(2x) = 161
Now simplify
5) 4x + 17 = 161
Solve x by subtracting 17 from both sides.
6) 4x = 161-17
4x = 144
So x= 144/4
X=36
Now remember, Jack's equation was (x+17) so we are now able to substitute x into the equation. Since we found x = 36,
Jack = (36 + 17)
Which equals to 53.
So jack's score was 53!
