54/18 is an improper fraction. It means that the numerator is greater than the denominator. To simplify and improper fraction, it must become a mixed fraction, a combination of a whole number and a proper fraction.
54/18. we need to use long division.
_<u>03</u>

54/18 = 3 Whole number because there is no excess.
Answer:
its B
Step-by-step explanation:
The equation 4x = y is solve for y so we can substitute the expression 4x for y in the other equation.
2x² - (4x) = 0 ← Substituted 4x for y...Hug'em when you plug'em (use ( )s)
2x² - 4x = 0 ← prepare to factor
2x(x - 2) = 0 ← factored out the GCF
2x = 0 or x - 2 = 0 ← zero product property
x = 0 or x = 2 ← solved each mini equation
If x = 0, then y = 4(0) = 0. (0, 0) is a solution
If x = 2, then y = 4(2) = 8. (2, 8) is a solution
The solution set is {(0,0), (2,8)}
Children will use the Make a Ten strategy in this lesson, along with
other strategies. Remind children that if they are adding two numbers
such as 8 + 5, they can regroup the numbers to make adding easier. Tell
children that they can take 2 from the 5 and add the 2 to 8 to make a
ten. Also remind them that they must remember to subtract the 2 from the
5, leaving a 3, so they add 10 and 3 and get 13. Tell children that
they will use this strategy to add two-digit numbers.
Materials: overhead projector, ten-frames and
counters, tens and ones workmat, bundles of 10 craft sticks and single
sticks, large number line, and large hundred chart
Preparation: Prepare a tens and ones workmat and a
ten frame for use on the overhead. Make 9 bundles of craft sticks, 10
per bundle, using rubber bands to hold them together. Or use tens and
ones blocks. Make a large number line and hundred chart for the
classroom.
Prerequisite Skills and Concepts: Children should know the addition facts to 20 and the strategies used in learning them.
