Despite his name, Mr. Bean likes to eat lots of fruit. He finds that four apples and two oranges cost £1.54 and that two oranges
Iteru [2.4K]

The cost of one apple, one orange and one banana is $0.81

To solve this equation, we would write out equations on this.

  • let x represent apples
  • let y represent orange
  • z represent bananas
<h3>What is an Equation</h3>

This is a mathematical statement used to represent word problems.

4x+2y=1.54...equation(i)\\2y+4z= 1.70...equation (ii)

when we add both equations, the resultant value is

4x+4y+4z=3.24

We can further divide through by 4 to know the cost of one apple, one orange and one banana

\frac{4x+4y+4z}{4}=\frac{3.24}{4}\\ x+y+z=0.81

It would cost Mr. Bean $0.81 to purchase one apple, one orange and one banana.

Reptile [31]

Answer:

\frac{14}{15}

Step-by-step explanation:

\frac{4}{5} × \frac{3}{9} + \frac{2}{3} ( firstly, multiply the 2 fractions together )

= \frac{12}{45} + \frac{2}{3}

= \frac{4}{15} + \frac{2}{3}

= \frac{4}{15} + \frac{2(5)}{3(5)}

= \frac{4}{15} + \frac{10}{15}

= \frac{14}{15}
