Answer 2

Sure, here are the solutions:

To simplify the expression (1/36 - 3/14) - 6/35, we first need to find a common denominator for all three fractions. The least common multiple (LCM) of 36, 14, and 35 is 1260.

1/36 can be converted into 35/1260 by multiplying the numerator and denominator by 35/1.

3/14 can be converted into 225/1260 by multiplying the numerator and denominator by 90/6.

6/35 can be converted into 216/1260 by multiplying the numerator and denominator by 72/5.

So, (1/36 - 3/14) - 6/35 can be written as:

35/1260 - 225/1260 - 216/1260

Now, we can combine the numerators and simplify:

(35 - 225 - 216)/1260 = -406/1260

The expression simplifies to -203/630 in its lowest terms.

Therefore, (1/36 - 3/14) - 6/35 = -203/630.

To simplify the expression 5/14 - 0.3 + 1/7, we need to convert the decimal 0.3 into a fraction with a common denominator.

0.3 can be written as 3/10. To find a common denominator for 5/14, 3/10, and 1/7, we can multiply the denominators together:

14 * 10 * 7 = 980

So, we can convert 5/14 to 350/980 by multiplying the numerator and denominator by 25/25, convert 3/10 to 294/980 by multiplying the numerator and denominator by 98/98, and convert 1/7 to 140/980 by multiplying the numerator and denominator by 20/20.

Therefore, 5/14 - 0.3 + 1/7 can be written as:

350/980 - 294/980 + 140/980

Now, we can combine the numerators and simplify:

(350 - 294 + 140)/980 = 196/980

The expression simplifies to 1/5 in its lowest terms.

Therefore, 5/14 - 0.3 + 1/7 = 1/5.
