Name two mixed numbers that the sum is 8 4/8 and the difference is2 2/8

timama [110]

I will change them back to mixed numbers, I just work better with decimals.
F= first number
S= second number
f+s=8.5
f-s=2.25
-2s=-6.25
s=3.125
8.5-3.125= 5.375
The numbers are 3 1/8 and 5 3/8.

How many groups of 1/2 days are in 1 week? Write a multiplication equation or a division equation to represent the question, the

worty [1.4K]

Answer:

14 groups

Step-by-step explanation:

Given

$Groupings = \frac{1}{2}\ day$

$Duration = 1\ week$

Required

Determine the number of group in the week

To do this, we simply divide the duration by the number half day group.

This gives:

$Group = \frac{Duration}{Groupings}$

$Group = \frac{1\ week}{1/2\ days}$

Convert week to days

$Group = \frac{7\ days}{1/2\ days}$

$Group = \frac{7}{1/2}$

$Group = 7 / \frac{1}{2}$

Convert to multiplication

$Group = 7 * \frac{2}{1}$

$Group = \frac{14}{1}$

$Group = 14$

<em>Hence, there are 14 groups</em>
