• GUYS This is very easy,7/10=70/100 add 13/100 the final nuber is 83/100
• thanks for telling me
• wow this is like addition! But with fraction!
• if 7/10 is 70/100 what is 70/10, 700/100?
• Yep! A really easy way to see if 70/10 and 700/100 are equivalent is solve them. 70/10 is equal to 70 divided by 10. The quotient is 7. 700 divided by 100 is also 7. Now we know that they are both equivalent.
• the colors look different
• but it looks like you multiply both numerator and denominator by ten
• I couldn't figure it out when I stopped the vidio.Could you
• it is like this, first turn the 10's into 100' by multiplying by ten then add normally like 8/10 + 14/100 so 8x 10 = 80 and 80+14=94 so 94 is the answer
