Question:

Three students were working on 630,000÷700 in math class.

a. Desiree finds the quotient is 9,000 and Micah finds the quotient is 900.

Determine which student found the correct quotient.

b. Delilah finds her answer is 90, but she copied the expression incorrectly from the board. If her reasoning and answer for the expression she copied are correct, what expression might she have written?

Answer:

a. Micah is correct

$Expression = 63000 \div 700$

$Expression = 630000 \div 7000$

Step-by-step explanation:

Given

$Expression = 630000 \div 700$

$Desiree = 9000$

$Micah = 900$

Solving (a): Who is correct?

To do this, we first calculate the quotient of the expression.

$Expression = 630000 \div 700$

Divide 630000 by 700

$Quotient = 900$

Hence:

Micah is correct

Solving (b): What Delilah must have copied?

We have:

$Delilah = 90$

There are no options to pick from. So, we just need to work out expressions that equals 0.

Possible expressions are:

$Expression = 63000 \div 700$

$Expression = 630000 \div 7000$

5. A hummingbird feeder holds 2/3 of a cup of hummingbird solution. A bottle of solution will fill the feeder 8 times. How much

alina1380 [7]

Answer:

1.26 liters.

Step-by-step explanation:

Given that, a hummingbird feeder holds $\frac{2}{3}$ of a cup of hummingbird solution.

Again, a bottle of solution will fill the feeder 8 times.

Therefore, a bottle of solution will measure $(\frac{2}{3}\times 8) = \frac{16}{3} = 5.33$ cups of hummingbird solution.

Now, one cup is equivalent to 0.236588 liters.

So, 5.33 cups is equal to (0.236588 × 5.33) = 1.26 liters. (Answer)
