Answer:

The three integers are 81,82 and 83

Step-by-step explanation:

Let

x,x+1 and x+2 ----> the three consecutive integers

we know that

$x+(x+1)+(x+2)=246$

Solve for x

$3x+3=246$

$3x=246-3$

$x=243/3$

$x=81$

therefore

$x=81$

$x+1=81+1=82$

$x+2=81+2=83$

A chef cooked 5 kilograms of mashed potatoes for a dinner party. If the guests only ate 4/12 of the amount he cooked, how much d

balandron [24]

Answer:

$1\frac{2}{3}\ kg$

Step-by-step explanation:

we know that

To find out how much the guests ate, multiply the total amount of kg of mashed potatoes by the 4/12 fraction

$5(\frac{4}{12})=\frac{20}{12}\ kg$

convert to mixed number

$\frac{20}{12}=\frac{12}{12}+\frac{8}{12}=1\frac{8}{12}\ kg$

simplify

$1\frac{8}{12}=1\frac{2}{3}\ kg$
