Answer:

\sf 61\frac{1}{20}

Step-by-step explanation:

Given expression:

\sf 63 \frac{1}{4}-2 \frac{1}{5}

<u>Partition</u> the mixed numbers into <u>fractions</u> and <u>whole numbers</u>, and then subtract them separately.

<u>Subtract</u> the whole numbers:

\implies \sf 63-2=61

<u>Subtract</u> the fractions by changing both fractions into equivalent fractions so both fractions have the <u>same denominator</u>:

\implies \sf \dfrac{1}{4}-\dfrac{1}{5}

\implies \sf \dfrac{1 \times 5}{4 \times 5}-\dfrac{1 \times 4}{5 \times 4}

\implies \sf \dfrac{5}{20}-\dfrac{4}{20}

<u>Subtract</u> the numerator:

\implies \sf \dfrac{5}{20}-\dfrac{4}{20}=\dfrac{1}{20}

Put the two answers from the whole numbers and fractions back together:

\implies \sf 61+\dfrac{1}{20}=61\frac{1}{20}

Therefore:

\implies \sf 63 \frac{1}{4}-2 \frac{1}{5}=61\frac{1}{20}

Pls help me with this
astra-53 [7]

Answer:

the third one!

Step-by-step explanation:

Because it says, the SUM of the number, x (or z I can't really see it well) and 1/2, you must add those two together:

1/2 + x

Then it says those two numbers equal to 4, so it would look like this:

1/2 + x = 4

Because you are trying to isolate, and solve for x, you must SUBTRACT 1/2 from both sides of the equal sign:

1/2  +  x  =  4

-1/2            -1/2

1/2 minus 1/2 would result 0, so there would be x by itself. and 4 minus 1/2 would be 3 and a half ( 3  1/2), so x would be  3  1/2

x = 3 1/2

Hope this helped. If this is incorrect please specify so I can help :)

What is x+2/x * 10/30
Ganezh [65]
X + (2 10)/(30 x)
The gcd of 10 and 30 is 10, so 10/30 = (10×1)/(10×3) = 10/10×1/3 = 1/3:
x + 2/(3 x)
Put each term in x + 2/(x 3) over the common denominator 3 x: x + 2/(x 3) = (3 x^2)/(3 x) + 2/(3 x):
(3 x^2)/(3 x) + 2/(3 x)
(3 x^2)/(3 x) + 2/(3 x) = (3 x^2 + 2)/(3 x):
Answer:  (3 x^2 + 2)/(3 x)
