kayla used 4/10 of her allowance to buy yogurt and 5/10 to go skating. what fraction of her allowance does kayla have left? explain

Respuesta :

She started with her whole allowance - all 10/10 of it. After she spent 4/10, she was left with 10/10 - 4/10 = 6/10, and after spending another 5/10, she’ll finally be left with 6/10 - 5/10 = 1/10 of her allowance.
