Noah spent some of his allowance on monday. he spent 1/6 of his allowance on tuesday and 3/6 of it on friday. noah has none of his allowance money left. what fraction of his allowance did he spend on monday?

Let us represent the allowance spent by Noah on Monday by the letter "x".

We know that all the fractions must always add up to 1 in such questions.

Thus, if Noah spent 1/6 of his allowance on Tuesday and 3/6 of it on Friday and he spend x amount on Monday, then these spendings must add up to 1.

In other words,

Thus,

Thus Noah spent a third or of her allowance on Monday.

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
