Answer:

3 is the whole number

2 is in the decimals place which will be our numerator

the value of the 2 in the decimal's place is 10 so that will be our denominator

You'll be left with:

3 2/10 = 3 1/5

THE RATIO OF ANNUAL INCOMES OF A AND B IS 4 :3 AND THEIR ANNUAL EXPENDITURE IS 3 :2 IF EACH OF THEM SAVES SHILLINGS 1000 A YEAR

pickupchik [31]

Answer:

Annual Income of A= $4x=4*1000=4000$

and

Annual Income of B= $3y=3*1000=3000$

Step-by-step explanation:

Given Data:

Ratio of annual income of A and B=4:3

Ratio of expenditures of A and B=3:2

Saving of A and B=1000

Required: Annual Income of A and B=?

Solution:

If ratio of income of A and B is 4:3

then let Income of A= $4x$ and Income of B= $3x$

If ratio of expenditure of A and B is 3:2

then let expenditure of A= $3x$ and expenditure of B= $2x$

Therefore,

$4x-3x=1000$ ........... $Eq(1)$

and $3x-2x=1000$ .......... $Eq(2)$

subtracting Eq(1) and Eq(2), we get

$4x-3y=1000\\-(3x-2y)=1000\\......................\\x-y=0$

$x=y.....Eq(3)$

putting $x=y$ in Eq(1), we get value of $x$ as

$4x-3x=1000$

$x=1000\\thus, y=1000 \\$ because x and y are equal in Eq (3)

Now, Annual Income of A= $4x=4*1000=4000$

and Annual Income of B= $3y=3*1000=3000$

What is the value of 100?

Nesterboy [21]

Answer:

Step-by-step explanation:

Means back the numbers into multiples of several small numbers

Like:; 1. We take LCM of 40

Just break into multiples of small number

40= 2×2×2×5

2. We take LCM of 50

50= 5×5×2

So LCM for 100 is 2×2×5×5

after that see the pairs in the LCM like 2×2 or 3×3 or 4×4(same numbers)

Then write the the single number in place of two multipled numbers

Like:; 2×2 is written as 2 // 3×3 is written as 3

So we can write 100 into 2×2×5×5 and then after selecting pairs (2×2)×(5×5)

write pairs in single number 2×5

And so we get 2×5=10

So we find root of 100 that is 10
