97 rounds up to 100
78 rounds up to 80
100x80= 8,000
estimate=8,000
97x78=7,566
product=7,566
So 1.5 means 1 and 1/2 or 2/2+1/2=3/2
and 1=x/x where x=x so 1 could be 1/1 or 3/3 or 2342/2432 and so on
for simplicity just use 1/1
to multiply fractions just multiply the top numbers by the top numbers and the bottom numbers with the bottom numbers so
3/2 times 1/1=(1 times 3)/(1 times 2) or the same thing since anything times 1 is the same thing so the answer is 3/2 or 1 and 1/2
If i read that correctly, the answer should be 6.372 in standard form
For this problem, we are given a vector and we need to sketch two variations of it.
The vector is:
We need to sketch -2v and 1/5 v.
The coordinates for -2v are <2, -10> and for 1/5 v they are <-1/5,1>
