Find the value of each expression if x= 1/4 y= 3/5 and z= 2/3
28.z divided by 2
1/3
30. z divided by x= 2 2/3
32. 5 divided by y= 3
32 is wrong
5/(3/5) =
(5/1)*(3/5)
flip and multiply
(5/1)*(5/3) = 25/3
28 and 3 are right
32 is wrong
28 and 30 are right
8 1/3 for 32
Right.
To find the value of each expression using the given values of x, y, and z:
1) The expression 28.z divided by 2:
To find the value of this expression, we need to multiply the value of z (which is 2/3) by 28, and then divide that result by 2.
Value of expression = (28 * (2/3)) / 2
= (56/3) / 2
= (56/3) * (1/2)
= 56/6
= 28/3
≈ 9.33 (rounded to two decimal places)
Therefore, the value of the expression "28.z divided by 2" is approximately 9.33.
2) The expression 1/3:
The value of this expression is already given as 1/3.
Therefore, the value of the expression "1/3" is 1/3.
