Well, the largest set it belongs to is the set of all real numbers - numbers which can be written on the number line. -5 is of the set of rational numbers since it can be written as a fraction (-5/1 for example). It is an integer since it is a whole number. Thus:

-5 ∈ <span> ℤ (</span>Integers) ∈ ℚ (Rational Numbers) ∈ <span>ℝ (Real Numbers)</span>

7/8 times 1/3 times 2/5
allsm [11]

Answer:

7/60

Step-by-step explanation:

7/8 times 1/3 is 7/24.

Then, 7/24 times 2/5 is 7/60

When multiplying fractions you just multiply across. For example, 7/8 times 1/3. 7 times 1 is 7 and 8 times 3 is 24. So, 7/8 times 1/3 is 7/24.

Hope this helps :)
