Answer:

222

Step-by-step explanation:

Let x be the number on Shante's doors. The units in Shante's apartment complex are consecutively numbered on each floor, so the number on next door is x+1.

The sum of these numbers is 443, then

x+(x+1)=443\\ \\x+x+1=443\\ \\2x+1=443\\ \\2x=443-1\\ \\2x=442\\ \\x=221\\ \\x+1=221+1=222

The larger of two numbers is 222.

What is 7/8 divided by 1/8
eduard

Answer:

7

Step-by-step explanation:

<u>Concepts:</u>

  • Division: a system of distributing a collection of things into equal parts
  • Fractions: #s that represent a part of a whole
  • Dividing Fractions: dividing a fraction by another fraction = multiplying the fraction by the inverse (reciprocal) of the other one
  • Inverse Operations: operations that are opposite of each other (e.g. inverse of addition is subtraction)

<u>Solving:</u>

1. First, let's set up the equation:

7/8 ÷ 1/8

2. We can get the reciprocal of 1/8 by doing the opposite of division; multiplication. 1/8 becomes 1 · 8, and that's equal to 8.

3. Now, since we know dividing a fraction by another one is exactly the same as multiplying the fraction by the reciprocal of the other, let's multiply 7/8 by the inverse of 1/8, which is 8.

7/8 · 8 = 56/8 = 7

Therefore, 7/8 divided by 1/8 is equal to <u>7</u>.
