How much is three half’s plus one fifth

Let's make it an expression.

Three half's= 3/2 Plus= + one fifth= 1/5

We need to turn 3/2 and 1/5 so that they have the same denominator. Let's use 10.

3/2→15/10 1/5→2/10

15/10+2/10=17/10=1 7/10

So, three half's plus one fifth is 1 7/10.

Your answer is 3.1. the way this is done is you find a number that both of the denominators can go into, in this case 10. multiply the 2 in 1/2 by 5, and the 5 in 1/5 by two. so now your problem should look some thing like this. 3 1/10 + 1/10. combine your 1/10's so you have 3 2/20. multiply 3x20+2 62/20, 3.1

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
