Answer:
-1 1/5
Step-by-step explanation:
<em>Change the whole number 4 to an improper fraction</em>
-4 4/5 ÷ 4/1 = -4 4/5 ÷ 4/1
<em>Reciprocal the 4/1 will become 1/4 then go to multiplication</em>
-4 4/5 ÷ 4/1 = -4 4/5 × 1/4
<em>Change to improper fraction the -4 4/5</em>
-4 4/5 ÷ 4/1 = -24/5 × 1/4
<em>Then simply multiply the two numerators and the two denominators</em>
-4 4/5 ÷ 4/1 = -24/20
<em>Finally, Simplify it to get the answer</em>
-4 4/5 ÷ 4/1 = -1 1/5
you spend 28 and want 20 profit
28 +20 = 48 total
48/4 = 12

Answer:
Step-by-step explanation:
sports store sells three different packs of tennis balls. Brand A costs $2.50 for two balls, brand B sells three balls for $3.90, and brand C has a sale of four balls for $5.12. Which inequality about the unit price per ball is correct
Brand A:
$2.50 for 2
Brand B :
$3.90 for 3
Brand C:
$5.12 for 4
We calculate the unit price :
Brand A:
$2.50 / 2 = $1.25
Brand B:
$3.90 / 3 = $1.30
Brand C:
$5.12 / 4 = $1.2
Answer:
The single decimal multiplier used to increase by 18% followed by a 12% decrease is 0.21.
Step-by-step explanation:
Let 'x' be the number
As first the number has to be increased by 18%
so
Step 1: write the percentage '18%' in decimal form
18% = 0.18
Step 2: For percentage increases: add the decimal to 1
1 + 0.18 = 1.18
Step 3: Multiply the number x by the multiplier, found in Step 2
x × 1.18 = 1.18x
<u><em>NEXT WE HAVE TO DECREASE 1.18x by 12%</em></u>
Apply the same method but with a number 1.18x
- Write the percentage '12%' in decimal form
12% = 0.12
- For percentage decreases: subtract the decimal to 1
1 - 0.18 = 0.18
- Multiply the number 1.18x by the multiplier, found in Previous step
1.18x × 0.18 = 0.21x
Therefore, the single decimal multiplier used to increase by 18% followed by a 12% decrease is 0.21.
