Types of gravel include: 1  Bank gravel: naturally deposited gravel intermixed with sand or clay found in and next to rivers and streams. 2  Bench gravel: a bed of gravel located on the side of a valley above the present stream bottom, indicating the former location of the stream bed when it was at a higher level.
You can multiply the numerator and the denominator by 4, as shown in part B above. But you cannot multiply the numerator by 4 and the denominator by 2. The numerator and the denominator of a fraction must be multiplied by the same nonzero whole number in order to have equivalent fractions.You may be wondering why this is so.xample 4. Multiplying the numerator and the denominator of a fraction by the same nonzero whole number will change that fraction into an equivalent fraction, but it will not change its value. Equivalent fractions may look different, but they have the same value. Let's look at some more examples of equivalent fractions.
So we know that 3/4 is equivalent to 9/12, because 3Ã12=36 and 4Ã9=36. A simple way to look at how to check for equivalent fractions is to do what is called âcross-multiplyâ, which means multiple the numerator of one fraction by the denominator of the other fraction.nd yes grasshopper, 2/4 is an equivalent fraction for 4/8 too.As you already know, we are nuts about rules. So, letâs look at the Rule to check to see if two fractions are equivalent or equal. The rule for equivalent fractions can be a little tough to explain, but hang in there, we will clear things up in just a bit.
