2 & 1/6 x 2 & 5/6 <br><br> Plz solve I keep getting it wrong

Gre4nikov [31]

Answer:

6 $\frac{5}{36}$

Step-by-step explanation:

Turn all fractions to improper fractions first.

2 $\frac{1}{6}$ × 2 $\frac{5}{6}$ = $\frac{13}{6}$ × $\frac{17}{6}$

Directly multiply. (numerators with numerators and denominators with denominators)

$\frac{13}{6}$ × $\frac{17}{6}$ = $\frac{221}{36}$

Simplify by turning improper fractions back into mixed numbers.

$\frac{221}{36}$ = 6 $\frac{5}{36}$

If 1/3 of an office staff is on vacation and 1/4 of those not on vacation are out sick, what fraction of the staff is in the off

diamong [38]

Let x be the total number of staff in the office.

Thus,

The number of staff on vacation = $\frac{1}{3} x$

Since, it says that staff out sick are among those not on vacation, we have to subtract the number of staff on vacation from the total number of staff.

The number of staff out sick = $\frac{1}{4} (x - \frac{1}{3}x)$

Hence,

The number of staff in the office = $x - \frac{1}{3} x - \frac{1}{4} (x- \frac{1}{3} x) = (x - \frac{1}{3} x)(1 - \frac{1}{4} ) 
= x(1- \frac{1}{3})(1- \frac{1}{4}) = x( \frac{2}{3})( \frac{3}{4})$ $= \frac{1}{4} x$

I need help what is y?

Darina [25.2K]

Answer:

$y=-5.6$

Step-by-step explanation:

$2.5\left(y + \dfrac{2}{5} \right) =-13\\\\\textsf{divide both sides by 2.5} : y+ \dfrac{2}{5}=-5.2\\\\\textsf{subtract} \ \dfrac{2}{5} \ \textsf{from both sides} : y=-5.6$
