What is two and three hundreds seventy thousandths in decimal form
givi [52]

Answer:

2.370

Step-by-step explanation:

In this, the word "and" means the decimal point so:

two and 3

=

2.3

so the tenths place would be the first number after the decimal point, you can think of it as counting backwards. 1000  100  10  "0"  0.1  0.01  0.001

                                                thousnd hundrd tn zro tnths hundrds thousndths

so the 3 hundred would be 0.3 and the sevenTY thousandths would be 0.070

so add that all up and you get:

2.370

or

two and three hundreds seventy thousandths

Hope this helped! Pls Brainliest! It would help and mean a lot! ; )

Strike441 [17]

Answer:

5 11/12 cups of melon

Step-by-step explanation:

The cups of melon he puts in the fruit salad is:

3 + 2 + (1/4 + 2/3)

The Least common denominator is 12

5 + (3 × 1 +4 × 2/12)

5 + (3 +8/12)

5 11/12 cups

Therefore, Jason put in 5 11/12 cups of melon in the fruit salad.
