there were 420 birds migrating to the south in the sky this morning. If the ratio of Godwits to Geese in the sky this morning was 20:40, how many more Geese were there than Godwits in the sky?
first, add 20 and 40. that gives you 60. then, you divide- 420/60. that gives you 7. then multiply 7 by 20, giving you 140, and multiply 7 by 40, giving you 280. then subtract: 280-140
