Decimals greater than one. write in word form and expended form for each for 2,51

In word form - "Two and fifty-one hundredths." In expanded form - 2 + 0.5 + 0.01.

Step-by-step explanation:

To write a decimal in word form, we write out the words we would say as we read the decimal. When we read a decimal, we read the whole number before the decimal. This is "two." The decimal is read as "and." After this, we read the digits behind the decimal as a group; 51 would be read as "fifty-one", and since 1 is in the hundredths place, it is "fifty-one hundredths."

To write a number in expanded form, we separate the digits by place value. 2 is in the ones place, so it equals 2. 5 is in the tenths place, so it equals 0.5. 1 is in the hundredths place, so it equals 0.01. Together this gives us:

2 + 0.5

homozygous. one is homozygous, while two is heterozygous.
