Help me with math questions urgent Thanks

Answer:  x = 2.65, y = 3.81

Step-by-step explanation:

          ABC similar to PQR

1) Find the ratio of corresponding sides

2) Use that ratio to find values for x & y

        1) Side AB = 2.76cm & Side PR = <em>y</em><em> </em>cm

             Side BC = <em>x</em> cm & Side RQ = 3.66 cm

         Side CA = 3 cm & Side QP = 4.14 cm (both lengths given)    

Can match 3 to 4.14 & ratio of sides in ABC to PQR= 3 /4.14

Length of sides ABC = 3/4.14 times the length of sides PQR

           2)  x = (3 / 4.14) * 3.66 = 2.65

            Now solve for y, ABC to PQR:  2.76 = (3 / 4.14) (<em>y </em>)

<em>equality property</em> (both sides) & inverse operation to isolate <em>y : </em> .               2.76 ÷ (3 / 4.14) = (3 / 4.14 ) ÷ (3 / 4.14) (<em>y</em><em>)</em>

              2.76 * (4.14 / 3) =  3 / 4.14 * (4.14 / 3) (<em>y</em><em>)</em>

                     (2.76 * 1.38 ) =  3.81  = <em>y</em>

<em></em>

What is the least common denominator for 2/3 and 3/5
ivolga24 [154]

Answer: 15

Step-by-step explanation: The common denominator for these 2 fractions is simply the least common multiple for the 2 denominators.

To find the least common multiple or <em>lcm</em> of 3 and 5, we begin by listing the first few multiples of each number.

<em>Multiples of 3</em>

1 x 3 = 3

2 x 3 = 6

3 x 3 = 9

4 x 3 = 12

5 x 3 = 15

We skipped 0 x 3 because our lcm can't be 0.

Next we list the multiples of 5.

<em>Multiples of 5</em>

1 x 5 = 5

2 x 5 = 10

3 x 5 = 15

Notice that 15 appears in both lists so

our least common denominator is 15.
