Answer:
A significant figure is the first digit in a number that isn't zero. You round to this.
Step-by-step explanation:
E.g. 1959302 to 1 Sig Fig = 2000000
You round to the first figure that isn't zero, which is one
E.g 0.000001373 to 1 Sig Fig = 0.000001 because that 1 is the first digit that isn't zero
545,999 rounded to the nearest hundred thousand is 546,000.
Amount of potatoes that Zoe has = 5 pounds
Quantity of potatoes that Zoe need for each recipe = 5/(3/4)
= 5 * (4/3)
= 20/3
= 6 2/3
From the above deduction, we can conclude that only 6 recipes can be made. The remaining amount of 2/3 will remain unused. I hope the procedure is clear enough for you to understand.
