Numbers with three digits – sometimes the noun which is counted is repeated with every digit (מאה שנה ועשרים שנה ושבע שנים - a hundred and seven and twenty years)¹⁵⁰. And sometimes not.

footnotes: ¹⁵⁰ Genesis 23:1.

And the sages of blessed memory interpret that any place where the noun that is counted is repeated, it comes to compare the noun in a certain matter, in accordance with Rule 144 regarding nouns that are repeated.

Indeed, when the noun מְאַת (hundred of) as a construct cardinal has with it numerals representing tens and ones and the name מְאַת comes before these other numerals – that which is counted must be repeated, since a noun that is in construct state must come right after its corresponding noun without a break.

Genesis 25:7 says, ואלה ימי שני חיי אברהם אשר חי מאת שנה ושבעים שנה וחמש שנים (And these are the days of the years of Abraham's life which he lived, a hundred seventy-five years), using the words מאת שנה ושבעים שנה וחמש שנים for “a hundred seventy-five years”, where the noun which is counted שנה (year) is repeated, in accordance with Rule 77.
