@Freya_24mU How about you look at the expression and you instantly see 1 …..instantly!
Why? Because any number raised to 0 exponential is 1
If you know that “fact” you see the expression reduces to 4/4
@Emily_53xl You can do this in your head in under 10 seconds by recognizing that the first number is three and the second number is 1/2.
Just understanding this rule: if you divide by a fraction then you’re going to multiply by the reciprocal.
the answer is
3 divided by 1/2 is 3x2=6
Wow! Am I the only one who got this one right? For those of you who think the answer is 90, look carefully: it didn’t say divide 70 by 2- it says divide 70 by 1/2.
70 ÷ (1/2) = 70 × (2/1) = 140
140 + 55 =195
Look at it this way: If you have a pizza cut into 10 pieces, and you divided collectively those slices in half, you would have a total of 20 slices.
@farman4x This is not a hard problem Its something if you saw on an SAT test it would take you 20 seconds to solve if you were a normal college bound student.
